Virus Alert: You have received a Christmas Greeting Card!

Tonight I've received dozens of emails with the subject You have received a Christmas Greeting Card! and felt is was appropriate to advise everyone.

These emails are fake and carry malware. Norton Internet Security (the current anti-virus software I'm testing) didn't pick up the malware. Microsoft's Security Essentials identified and deleted the malware once it was saved to the computer.

The email purports to be sent from and has an attachment with the file name Christmas Inside the zip file is an executable program with the name Christmas Card.doc.exe. The number of spaces is used so the extension exe is not easily visible and tricks people into believing they are receiving a Word document.

Using Microsoft Security Essentials and OzEfilter is an excellent way to identify these malware emails and to delete them safely at the mail server before they reach your computer.

You should immediately delete these emails if you receive them.

- Kelvin Eldridge

Update: It's now 8:10am and dozens more of these emails were received overnight. OzEfilter shows the infected emails coming from Korea, South Africa, Netherlands, France, United States and India, so this infection is worldwide. Norton Internet Security is now identifying and removing removing the malware.

Alert: eBay Motors - don't miss today's private deals !

Most of the time I report emails which have malware attached that is not picked up by the anti-virus software. However, since I've seen a number of emails with the subject eBay Motors - don't miss today's private deals !, I decided to investigate. This email looks like a scam.

The email consists of a single image file which if downloaded, contains mapped areas to make people feel there are email addresses they can click on. The link to in particular is not an actual link and another very good indicator the email is a fake.

Checking the origin of the email showed it came from the United Arab Emirates. Other similar emails have been received from Puerto Rico and Saudi Arabia. Again very good clues these emails are fakes.

My guess is the aim of the email is to trick people into responding to one of the email addresses provided, and if they can trick someone, they will.

You should immediately delete these emails, or have a product like OzEfilter delete the emails safely at the mail server and never receive them into your computer.

Clicking on the image potentially provides the sender with your IP address and if your computer/internet connection is not secure, may be a further exposure. Experienced users won't even bother to look at the picture before deleting the email. The sender may take looking at a picture as a clue to you being a less experienced user. I don't know how these people think and I suspect most people don't either. It is best to minimise your exposure where possible.

Dictonary. Oops. I meant dictionary.

As I mistyped the word dictionary today, I wondered about the many ways people may mistype the word dictionary.

The following are the misspellings I found.


If you’re not sure of the correct or preferred spelling of a word in Australia, you can now use Word Check to verify the spelling. You can find Word Check on the main page of JustLocal.

Hoax: Mobile Phone Numbers Go Public this month.

I received an email saying Mobile Phone Numbers Go Public this month and stating PASS THIS ON TO AS MANY PEOPLE AS YOU CAN.

This is a hoax. Do not send it on.

Before sending any emails on that suggest you send them on, do a quick check. It took a couple of seconds to check the Do Not Call site to see this was a hoax.

Take the time to check. Your friends will thank you for it. I've seen a number of people completely embarrassed when they realised they've be suckered with a hoax virus. A hoax virus often does no harm except it tricks people into taking action. One hoax virus we did see, tricked a person into deleting an important file off their computer, so they can be harmful.

OzEfilter is great way to catch these emails before they reach your computer. The email is from someone I don't know and is also from America. Both good indications the email is suspicious.

From what I read the Do Not Call register records your details for three years. Those who registered three years ago will need to re-register, or their telephone numbers will be available to telemarketers. I hadn't read anything about mobile numbers and felt this email was likely to be a viral hoax.

Norton Internet Security misses the following malware.

In the last week Norton Internet Security missed the following malware.

Subject: Shipping update for your order 254-71546325-658732
Attachment Shipping

Subject: Your friend invited you to twitter!
Attachment: Invitation

From: (faked email from myself)
Subject: Your Membership Details!
Attachment (Password protected: 2627)

From: (fake email from myself using non-existent email address)
Subject: Free one year trial
Attachment: (Password protected: 9176)

From: (fake email from myself using non-existent email address)
Subject: Free one year trial
Attachment: (Password protected: 4141)

All of these emails would have been deleted by OzEfilter at the mail server and never reached my computer.

No matter which anti-virus program you are using you have to always be careful. The latest malware and password protected zip files can get past the anti-virus software. Take care with all emails containing attachments.

In addition quite a few emails which are phishing attempts were also received with no warning. These emails would have also been deleted by OzEfilter. Do be careful of links in emails. Often the lead you to sites which may look legitimate, but are only designed to obtain your username and password details.

Please do take care.

Telstra's new broadband plans.

Recently I noticed Telstra was about to announce new broadband plans. Their plans for quite some time have lagged behind others in terms of value. Today the announcement hit the mainstream media.

The problem with mainstream media is they don't satisfy my insatiable desire for detailed information and don't provide links to the source information. But the media is great for letting you know what is going on in general. You can easily access the latest news from different sites using the NEWS link on JustLocal.

Detailed information enables us to make better decisions. I decided to hunt out the press release. The press release from Telstra contains all the details to satisfy my appetite for information. You can find Telstra's press release here.

As to whether or not Telstra's new plans are good really is up to each person to decide based on their needs and situation. Considering entry level plan comes from having 200MB to now having 2GB, Telstra had a woefully inadequate entry plan which forced most people I know to almost immediately switch to a much dearer plan. (They had no choice because they were locked into a contract.) At 2GB that is better, but the excess charges are still a real problem. I also consider bundling and lengthy contract periods to be a concern.

Do your sums, check the fine print and shop around. Then you'll know if the new Telstra plans are for you or not.

MyAnswers. Professional solutions to your computer problems

As an IT consultant I solve client's problems every day. I also get asked for my opinion many times during a week. I decided some years ago to document this information so more people could benefit at a lower cost, than asking me direct.

The solutions and responses are documented in the MyAnswers database and can be purchased for a small fee over the internet.

Most of us including myself search the internet for solutions. I've been known to search for hours to solve a problem. Along the way I see many solutions that are partially correct, incorrect, and some that are outright dangerous. The problem with most public forums is anyone can participate. Even the forums offered by leading software vendors contain substandard information. If you think about why the public forums may offer substandard information it is pretty obvious. The vendors want people to feel part, to participate. In doing so however the vendors aren't providing their professional advice and guidance, but letting those who participate share information. It saves the vendor time and money, and they appear to be helping users. In my experience much of the help provided if you're not experienced can be inadequate. Without experience it would be very hard to separate the real knowledge from the gossip.

On one forum for open source software which I participated in, one person offered their advice to users which I knew would corrupt a person's computer. To their credit they meant well, but passing on untested information that has been posted by others is a recipe for disaster.

MyAnswers are my notes of what I've done to solve a problem. The solution has worked for my clients and in most cases it will work for you. I say most, because a slight change in situation may mean a different solution is required. All solutions come with a money back guarantee, so if it doesn't work for you, you won't be out of pocket.

If you want solutions, rather than gossip, check out MyAnswers. If you want to see the latest issues other people are finding with their computers, then check out the Recent solutions page. You will find it makes interesting reading.

Why I've now added a password to Word Check?

We all use the internet as a great resource. Most of us, including myself, go from site to site, using what is provided and never once thinking about the business or person providing the information. It is free after all. This is neither a statement that this behaviour is either good or bad. It just is.

As the developer of the Kelvin dictionary used in Word Check, I estimate the Kelvin dictionary I am building will take around a thousand hours of research before it is at the level I am happy with and ready for general release. A thousand hours of time to give away to others is something I'd like to do, but sadly can't afford to do.

I've made the decision to focus on people who are interested in giving and receiving. Those who join my mailing list give a small amount of their time to hear what I have to say. To see if something I am doing has value for them. There is no cost to join the JustLocal mailing list. You do not have to buy anything unless it interests you. You won't get flooded with emails from me every day. Your information will not be provided to others.

I apologise in advance to anyone I may inconvenience. I do trust you'll understand my reasons.

Are you myopic with your spelling?

OK, I just had to write that headline. Most people really do get into their spelling habits and if their spelling is challenged, you can get into a pretty good argument. With my dictionary work I take a different tack. The Kelvin dictionary is my preferred spelling. I've spent hundreds of hours researching the preferred spelling in Australia and made decisions based on that research. The spelling is how I now spell. I often find I need to change my spelling habits based on the outcome of my research. How others spell is up to them.

Now I mentioned the word myopic, because whilst it does mean narrow-minded, it is also another word for short-sighted. When I researched the word myopic I felt it showed a little about what I'm trying to achieve with my work and I thought that was worth sharing.

The current spellchecking tools we have in many ways aren't helping us, and could be hurting us and our children's spelling. This is true for commercial and open source software.

Type the following into your favourite word processor or browser (assuming the browser has spellchecking) and see what your spellchecker does.


- Most software will suggest spell check. This is an incorrect spelling for Australia. However this usage is now so common (by around 26:1), it may end up be the correct spelling in time. Microsoft Word 2007 suggests spell check and spell-check. Both are wrong in Australia. The correct spelling is spellcheck. (For those who are interested, the correct American spelling is spell-check.)

shortsighted, short-sighted, shortsightedness, short-sightedness

- The correct spelling is short-sighted. For short-sightedness the Macquarie and Oxford dictionaries agree on the spelling. If you type in shortsighted, Microsoft Word 2007 will suggest both short sighted and short-sighted.

nearsighted, near-sighted, nearsightedness, near-sightedness

- The correct spelling is near-sighted. The Oxford dictionary suggests near-sightedness and the Macquarie suggests nearsightedness, as the correct spelling. Microsoft Word will accept all spelling variations and is thus incorrect with nearsighted.

What then is the correct spelling of nearsightedness/near-sightedness?

We can check usage in Australia, but the problem is the main tool people use for writing in Australia is Microsoft Word. The good thing is near-sighted has greater usage in Australia which makes that word easy. For nearsightedness/near-sightedness usage is low, but the version used most often is nearsighted.

If we check the dictionaries for far-sightedness and long-sightedness we find the Macquarie and Oxford agree with the word being hyphenated.

For consistency, and because in all other forms the hyphenated version is used, with the Kelvin dictionary, the hyphenated version of the word is included. The words nearsighted and nearsightedness are also added to the Microsoft Exclude file, so they will now appear as spelling errors for anyone using my Exclude file when the next version is released.

For a bit of fun, you might want to try typing the following into your word processor, or browser.

The room had a lovely vu.
I went to the school fait.

I think you'll be quite surprised with the result. One person asked me what black magic had I performed on their computer. They couldn't believe the result.

iPhone 3G/3GS battery life

An interesting thought came to me the other day which is: how long will the iPhone battery last before it needs to be replaced?

I decided to check the Apple site and whilst it has very good information on how much usage you'll get from a charged iPhone, lots of information on care of the battery, a statement the battery has a limited number of cycles, the glaring omission to me is: how many times the battery can be fully recharged, or cycles as they call it.

How many cycles before the battery needs to be replaced. I would have thought that figure should be clearly stated. Replacing a battery probably represents more than 10% of the cost of a phone, so the battery is a fairly expensive consumable.

The other question I have is: if the number of cycles is limited, then if I use the iPhone direct off the power whilst surfing the web using wireless, will that extend the battery life? The answer I think should be yes, but it would be good to confirm.

I've not yet found information from an authoritative source, but one site did indicate a figure of 400 cycles for the iPhone. That's probably a fair figure because if you are a heavy user of the iPhone, meaning the iPhone has to fully recharged each day, then the battery would need replacing in a little over a year. That would be expected based on the information I've read.

If we use the figure of 400 recharge cycles, and then the amount of usage time when using different features of the iPhone, you can get a good idea of how long a battery should last for you.

The battery usage information for the Apple iPhone 3GS is the following. (Credit for information: Apple web site.)

Talk time:
Up to 5 hours on 3G;
up to 12 hours on 2G

Standby time:
Up to 300 hours

Internet use:
Up to 5 hours on 3G;
up to 9 hours on Wi-Fi

Audio playback:
Up to 30 hours

Video playback:
Up to 10 hours

Whilst I haven't done any timing tests, I do find with my current limited use of the iPhone (it isn't my main phone at the moment), that I have to recharge every couple of days. My main usage is internet usage which could be a 1-2 hours a day spread over the day. Given the battery usage information, and that I do use the iPhone for internet usage, I should probably expect to replace the battery every 1-2 years. Most of my wireless internet usage is around the home, so if having the iPhone running off mains power extends the battery life as I expect it should, then I could probably extend the life of the battery to 2-3 years, which would be pretty good.

Interestingly for those looking at a second-hand iPhone, if it is more than 12 months old, they should probably budget for a replacement battery on top of their purchase cost. Those upgrading to new models and selling off their existing iPhone which isn't very old, might indicate they tend to be a power user.

The 3G battery information indicates shorter usage time by possibly 30%, which would result in a significantly shorter battery life. Out of curiosity I decided to check the recent iTouch models and they provide up to 6 hours of playback, which is shorter again. In my recent article on the iPhone versus the iTouch I gave my reasons for going for the iPhone. The battery life could be added as another reason.

It took a while to gather this information, but now having learnt what I need to know, I'm in a better position to know how I can extend the life of the battery, and possibly even avoid the need to purchase a replacement battery.

Annoying Optus DNS assist feature sending me to the page.

Optus recently introduced their DNS assist feature. What this means is if I type in a domain name which is missing a letter, or not quite right, I'm shown the Optus DNS assist page. For example if I type (which is missing an 'l') I go to the address

Optus say the following is their reason.

"This search service is designed to make your web browsing experience more productive. No software was installed on your computer for this service to work."

The problem is this doesn't make me more productive. I have deliberately disabled the feature in Internet Explorer so if I type an incorrect address, the address remains in the address area so I can quickly fix it.

Why Optus did this I can only offer an educated guess. If you check the page you'll see Yahoo!SEARCH. I would be fairly confident that Optus is making money from Yahoo advertising.

Optus is apparently happy to make my experience of the internet worse for a few cents they'll gain from Yahoo advertising.

When I say guess, Firefox makes around 85% of its income from Google by providing Google as the default page. This works out at around 30 cents per Firefox user a year. Optus is likely to make less. So for less than 30 cents a year from me, Optus has damaged my user experience and when my contract is up, this will be another reason I'll be reconsidering Optus.

To get around the problem I can do one of the following:

1. Use the Opt out feature which places a cookie on my computer.

The opt out feature is well hidden so check the links on the page.

This is a bad option because we have multiple computers in our home. They use different browsers (and sometimes multiple browsers on the one machine) and every now and then the cookies get cleared. It is also not a good option because it will still be going to the Optus page which is a waste of time.

2. Set the DNS to another address provided by Optus.

This is a poor solution as it means each computer has to be changed. I've found in the past other ISPs have changed their DNS servers, and when that happens, it creates problems. It means this change needs to be done to each computer. If I use the computer when at a different location, I don't know if this will cause problems or what performance hit I might take.

3. Set the DNS on the router.

This is something a lot of users would not know how to do. In fact without calling Optus support, a user would not know the password for the router.

The problem however is with the equipment provided by Optus, which is he CG814 wireless router by Netgear, there isn't an ability to change the DNS addresses. I could set up another DHCP server, but really that is not worth the time and effort.

Option 2 is unfortunately the only useful option.

A couple of weeks ago, which coincidently was when this change appeared to have occurred, I had a problem for about a week accessing certain sites. Things got very unstable and some of the companies I deal with were getting a lot of flack from me. I couldn't update the sites I maintain. These suppliers almost lost my business and it really wasn't their fault. I don't see why the equipment I've been using for nearly 18 months has now decided to have problems around the same time as Optus made a change.

As it turned out Optus support didn't know what the problem was so it was escalated. The problem was solved the next day by disabling one of the firewall features. I really thought this was a poor solution as reducing protection provided by the router is not ideal.

A client also mentioned to me their home service was having a problem accessing some pages and had been advised it was a router problem.

The cost to me was literally hours of time. If you've ever called Optus and waited on the support line you'll know the time involved. I had quite long discussions with two support groups to fix the issue. Had I not been a computer expert I would have been dismissed by the support people based on our conversation. I had checked the problem was verifiable across five different computers using various operating systems.

This earlier problem is documented in MyAnswers solution 1934.

The DNS assist feature is an annoying inconvenience. It may have additional side effects which I'm not aware off. I really think companies are getting too greedy and it will end up biting them. In this case it probably amounts to making another 30 cents out of me per year. Yes, per year. This estimate is based on the estimated revenue of the Firefox/Google arrangement. Every day I see the Optus screen is reminder to me Optus' interests are definitely placed well ahead of mine as the customer. If Optus annoys me enough (which they're close to) they stand to lose over $1,500 of my business. I hope they've done their maths, because it won't take many annoyed customers to leave, to erode whatever revenue they make from their DNS assist page.

To get around the problem use one of the three approaches above. Whilst not ideal, when dealing with big companies it is best to work around their problems. Next time your contract comes up is the time to think about walking. I'll certainly be seriously thinking about giving Optus the shove due to this and the quite numerous other problems I've had with them. (E.g. Being without a telephone for nearly a week I consider to be a big issue. They're lucky they had me tied to a contract.)

The alternate DSN addresses as provided by Optus are:

Customers in NSW, QLD, ACT should configure their resolvers with these two DNS server addresses, in this order:

• Primary DNS Server

• Secondary DNS Server

Customers in VIC, SA and WA should configure their resolvers with these two DNS server addresses, in this order:

• Primary DNS Server

• Secondary DNS Server

I also tried using Telstra's DNS servers, but found they didn't work. This is a concern. It may mean I'll have problems if when I connect to the internet in another location. Making the DNS server IP addresses fixed isn't a good idea for mobile computing.

I hope this article helps other work around this issue.

Check out Renée's pre-loved items on her MyTreasure page at

- Kelvin Eldridge

MyTreasure beta now available.

I enjoy selling, swapping and giving away my pre-loved goodies, so it made sense for me to write an application which would enable me to list my goodies on the internet. I've called the software MyTreasure and it is available for free from

With all the online auction sites now available, the usual response I get from people is why MyTreasure. What most people don't realise when they list on other sites is 30-40% of all items listed never get a response. I want to list a lot of items and those fees for no result can really add up.

I also want to encourage people to look for pre-loved treasures locally. I've often seen people buy things for a few dollars and rarely do they take into account the postage and packaging. I was told of a young person who got ripped off because the freight was many times more than the hat they bought.

MyTreasure now provides anyone with a tool to create their list of pre-loved items complete with the files required for displaying on the internet. For those with access to free space on the internet (and that's most people), they can now promote their pre-loved treasures for free. If you'd prefer to have someone else look after the hosting, then that option is also available.

Over the coming days I will be creating my list of treasures which you'll be able to find at

MyTreasure is beta software. If you're interested in helping by using the software and providing feedback, I'm happy to provide three months of free hosting.

Articles: Google docs

For some time I've been using Google docs as a handy online word processor and spreadsheet program. I thought I'd share a few of my experiences, so I wrote an article which shows how I've used Google docs.

Has your search facility been hijacked?

A very common issue I see with client's machines is the default search engine has been changed without their knowledge. In many instances it is simply they've downloaded an update which also includes the Google Toolbar. Unfortunately many updates from leading overseas companies providing the Google Toolbar don't provide the correct Google search engine for Australia. You know if this has happened to you when you do a search using Google and Pages From Australia is not an option.

In addition, many of the leading software providers try to seed users with their own software. Software the user will often never need, which consume resources and should be removed. So not only do you get the wrong version of Google search for Australia, but you also get unwanted applications installed in your computer.

A while ago I developed a option for Internet Explorer (a search provider) for my clients, which enables them to search for pages from Australia by default. Most people love searching for pages from Australia first because it reduces a great deal of clutter in the results. People also prefer to find products and services from Australia first.

From a support point of view, adding the search provider to clients' machines gives me a visual clue they are using the correct version of Google for Australia. One glance and I can see the words JustLocal Google (AU default) as shown in the following image.

When I open any client's machine and the words JustLocal Google (AU default) do not appear in the search field, I know the machine needs to be reviewed.

Companies like Google, Apple and Adobe when you install their software often include software you don't want or need. The real problem isn't so much the leading companies, the real problem is with other companies tricking a user into installing their search engine by default. A change of the search provider is often a good clue of a malware infection, and in these cases I often find a couple of programs (typically adware) which need to be removed from the computer.

If you are interested in checking for products and services from Australia as the default in Google, then check out the Fun with Search page and install the Google search provider for pages from Australia as the default. The extra benefit is you can easily see if a software provider has altered your search settings without you being fully aware.

Virus alert: You have received a Halloween E-card!. An old friend added you as a friend on facebook.

I've noticed an increase of the malware with the subject You have received a Halloween E-card!. Do be careful this Halloween or your computer might end up possessed.

Whilst I've only seen the email with the subject An old friend added you as a friend on facebook once, this is a reminder to be very careful with emails purporting to be from people you may know. Most of the time the aim is to trick you to install the software attached to the email. If a friend has added you to Facebook, then log on to Facebook where you will have received a notification, if in fact it is real.

These emails can be easily avoided using a pop mail account and OzEfilter. In the last two weeks I've received 53 emails which had malware attached, which wasn't detected by the commercial anti-virus software package. These emails would have been easily deleted by OzEfilter before ever reaching the computer.

Please take care with malware.

OzEfilter 1.8 now available

OzEfilter 1.8 is proving to be very popular amongst those who use it. It is our secret weapon against spam and malware and is now available at a reduced price.

The problem with anti-virus software is it waits until the malware is in your computer before it checks it. Then anti-virus software can't pick up the latest malware because it takes a couple of days for the solutions to be created and released to users.

OzEfilter isn't an anti-virus solution, but because you get to check your email at the mail server before you collect your email, it helps to avoid most of the unwanted emails. Based on the recent Face-off between the free anti-virus software packages, an ideal combination would be OzEfilter and Microsoft Security Essentials. That combination will give you excellent protection at minimal cost.

OzEfilter is now also a Virtual Profit Sharing opportunity. Our business model is to share our profit with those who help us by referring business. Not just once, but for the life of the customer relationship. VPS members using OzEfilter can now help spread the word about OzEfilter and receive not only our thanks, but cash as well.

A couple of ways I use OzEfilter that makes my life easier are the following. I've installed OzEfilter on a netbook which enables me to continuously monitor my emails when I'm not on my main computer. I've also used OzEfilter to monitor newsgroups and only keep emails which contain the subject for things I'm interested in. This has saved my hours in deleting unwanted newsgroup emails. Perhaps you have an interesting way you've used OzEfilter.

Thank you to everyone using OzEfilter. Your support really is the lifeblood of OzEfilter.

Amazon Kindle For PC beta

The eBook reader market is certainly getting some attention lately with Amazon's new Kindle reader and Barnes & Noble releasing their reader. What I thought was very interesting is Amazon is releasing the Kindle For PC beta application for Windows in November.

To me this makes sense. Why limit your potential sales to a dedicated hardware device such as the Kindle reader, when you can make books available the larger market. I've put my name down to be notified when the beta application is available and will be checking it out. If you're interested in the Kindle For PC beta you can register using this link.

Many books such as those written by Australian authors (as listed on the Book Project page), will mostly likely never be available via Amazon. The good thing for consumers is there is more choice. You can access Amazon's range, you can read PDFs directly on your computer, or you can purchase printed books. The choice is yours.

British (and potentially Australian) spelling now possible with Outlook Express.

Anyone using Outlook Express under Windows XP who upgrades to Office 2007, will find their Outlook Express spellchecker no longer works, unless they wish to spellcheck in French.

There has been a solution for those using American English, but those wanting to use British or Australian English didn't have a solution. Now they do.  I've now made available a program which extends the solution provided for American English which adds the British dictionary as an option. For Australians you need to have an older version of Office 97 (possibly 95) as you need a file from the CDs. Once you copy the file to the right folder you can then use the program I've written to enable the Australian dictionary.

You can find more information on the Outlook Express page.

iTouch or iPhone

Recently I purchased an iPhone and started to review the unit. Yes. The IT consultant in me never stops, but neither does the desire to share the information I learn. If you are about to purchase an iPhone, checking out the iPhone article is worthwhile.

As an example I purchased the iPhone, set it up and checked my location and the local map. That cost me around $28 and there was no warning. Something I had done on other mobile phones at no cost.

The iPhone is an excellent product, but as with all products it has strengths and weaknesses. As I explore the world of the iPhone I'll be sharing my experiences as a series of MyAnswers solutions. Had I known one trick I would have saved myself $28. I suspect others may fall for the same trap and it could easily cost them hundreds of dollars. Find out what I didn't know in the iPhone article.

Virus alert:,,,

Recently I completed the anti-virus face-off (comparing free anti-virus programs) and I found the anti-virus software with new malware, that after a couple of days they would generally find and remove the malware from emails purporting to be from,, or

You know the emails. They have subjects and attachments like the following:

Your friend invited you to twitter! / Invitation
You have received A Hallmark E-Card! /
Shipping update for your order 254-78546325-658742 / Shipping

Then recently something weird happened. I started to see emails with the same subject and malware attachments not being picked up as malware. Surely the anti-virus software knows about these malware attachments I thought. Now that was weird so I decided to check. 

As it turns out the files sizes are slightly different. My guess is the malware writers are changing the malware ever so slightly to get past the anti-virus software. This cat and mouse game between malware writers and anti-virus software vendors has been going on for months.

Normally I tell people not to worry about blocking malware as the creators continuously change the email address. But in this case the same (faked) email addresses have been used. If you don't use the services of the companies, or, then blocking the domains or filtering on the subject at the mail server may be a good way to handle these unwanted emails.

In my case I use OzEfilter so it doesn't matter how many times malware writers change the malware, since I don't want email from those email addresses, they simply get deleted at the mail server when I check the mail.

So if you think your anti-virus software is losing its memory, it isn't. The malware writers a simply changing the attachments to get past the anti-virus software.

Is it true that for every degree you decrease your thermostat you can save up to 15% off your heating bill?

I was recently asked "is it true that for every degree you decrease your thermostat you can save up to 15% off your heating bill?"

I'm not an energy expert, but I do tend to think things through since I have science training in my background. What concerns me about the statement is it doesn't ever seem to be backed by a link to appropriate research. In addition I've heard a figure of 10% mentioned a number of times.

I actually think there is a bit of trick to the figure. If you think things through you'll see it is probably a true statement, but it does require certain assumptions.

As an outright statement of fact, I'd guess it is probably misleading, unless put in context.

Why context?

In Melbourne let's check the average temperature for the past week. The average temperature has been 12C. The maximum 21C and the minimum 2C. I've seen a figure of 18-20C degrees as the suggested temperature to set the thermostat for Winter.

If the average temperature has been 12C and you set your thermostat at 18C then the difference is 6C. Each one degree is roughly 16.66%. Drop the thermostat by one degree to 17C and you'll save the suggested 15%. If you originally had the thermostat set to 20C then the difference is 8C and one degree change to 19C will be 12.5%.

So really a figure of 10-15% saving is probably realistic.

The assumption here I suspect is you leave your heating on 24 hours, 7 days a week. This approach means once your home is heated to a certain level your heating will cut in and out to maintain the temperature. The average then should tend to work out.

My question then is, is it better to leave your heating on 24 hours a day, or to only use your heating as required?

For example when we get up we often turn the heating on. Once everyone goes off to school or work we turn it off. Later at night we'll turn the heating on again for a few hours. The heating is thus running 4-5 hours a day and not 24 hours a day.

Is turning your heating off when not required a better approach?

I don't know the answer to that question and perhaps I should do a study for a couple of days using the two approaches. Whilst it won't be exact as the weather will change from week to week, it might give a good indication.

The reality however for us is if the heating was left on 24/7 the heater would turn on and off regularly during the night. We find the noise of the heating if we leave it on, to disturb our sleep. So from a practical point of view it wouldn't work for us.

In my case I recently determined that parts of my home were not used, but the heating vents were open. I decided to close unused vents and to only heat the parts of the home as required. Parts of our home often don't get used for days. For example sometimes we don't use the lounge dining area because the family is busy doing other things. I see this part of the house not being used for 2-3 days at a time. During the day the sun warms the area, so at times there is little reason to heat the area. The immediate effect of closing off vents was the areas with open vents heated up much more quickly.

My thought about the statement you can save 10-15% of your heating costs by reducing your thermostat by one degree is it is probably true, if it is based on your running your heating 24/7. I also think it is one of those shock figures marketers use because for most people it just seems unbelievable.

I could be completely wrong, but my gut feeling is using only what you need, when you need it, and in the areas you need it, possibly uses less energy than reducing the thermostat. Reducing the thermostat to a comfortable level and wearing appropriate clothes is also a good way to reduce energy usage.

I'd really like to see what my gas bill would be if I did run heating 24/7 compared with how I currently run my heating.

My yearly gas bill for the past two years (which includes heating and hot water) has averaged $616 a year. I've started closing off areas of my home that don't require heating and I'm interested in seeing how that affects the gas bill.

I know the pilot light on the gas heating uses perhaps 10% of the gas each year. I could turn off the pilot light during winter, but I've found relighting the pilot light to be an experience that is very frustrating. They've hopefully improved that in more modern heaters.

I often wonder how my bill compares with other people's gas bills and I wonder how others reduce their gas costs. I've been able to find some great ways to save money on electricity using the Energy Cost Calculator, so perhaps it is time to check out what can be done with saving gas.

If you have any tips or thoughts please feel free to share.

Save money with the Energy Cost Calculator.

For while I've noticed local councils and organisations saying they will change over your old light globes for low energy light globes, as long as you have three or more light globes and sign the energy credits over to them. Now I really don't know the full picture, but something doesn't feel right.

If the government wants us to be more energy conscious for the good of the planet, then perhaps the best way is to simply show us where the savings are. I decided to work out the costs of running appliances around the home and work out the payback period should I change old inefficient lights with more modern low energy lights. As it turned out the savings are pretty good.

For example in the family area I have a light with 2 x 40W globes (total 80W). I wanted to change these to 2 x 8W (total 16W) low energy globes which cost $9 for two on special. I estimate we use that light around two hours a day. Using the Energy Cost Calculator I worked out the payback period would be just over a year. Since the globes will last well over three years, after the first year I'm saving money. It makes sense to change the globes.

Armed with a low cost energy meter I've been able to work out areas in my home where I can make considerable savings, sometimes with a small change in habits. Sometimes with the purchase of an inexpensive piece of equipment. For example my TV/DVDs around the home cost about $38 a year when in standby. I tried powering off the TV/DVDs at the power point, but unfortunately that was hard because the power points aren't easy to get to. I'm also concerned constantly turning power points on and off will mean an electrician will need to be called in more often and that can be expensive. 

Recently I found a really neat device from one of my suppliers which is a remote control with three power packs. That is you can control each of the power packs separately with the one remote. If you plug the power pack into the wall and then the TV/DVD into the power pack, you can easily turn the power off and save the money standby uses. The aim for me is to do this around the house with the TV/DVDs and computers. The payback for each power pack is 4 months. After that I'm saving money. Nearly a hundred dollars a year when I'm using all three power packs.

If you're interested in the energy meter, or the remote controlled power points, you can find more information on the Energy Cost Calculator page.

As I find more ways to save money on energy around the home, I'll post the tips as comments. If you've got a good tip please feel free to post a comment. (Posts considered advertising will be discarded.)

Round 5 - Free Anti-virus face-off. Free AVG vs Avast Free vs Microsoft Security Essentials.

Today is the final day of the Free Anti-virus face-off. The combatants, AVG, Avast and MSE have performed well, but some of the challengers performed well and managed to bypass their defences. We also saw CA (Computer Associates) and OzEfilter perform well.

Let's begin round 5.

A total of 17 emails containing malware were received with 7 being unique in terms of the email subject and the attached file. Two emails with different subjects had the same attached file. The files and shows the virus writers dynamically change the file names based on the email addresses they are sending to, and thus the actual number of unique malware files is less.

Re: important website /


CA missed 0

AVG missed 0

MSE missed 0

Avast missed 1

OzEfilter missed 0

At the end of round 5 as a result of the free anti-virus face-off the results for the free software are:


1. MSE

2. AVG

3. Avast

Of the free software option the winner is Microsoft Security Essentials.

MSE being the winner is based on it being able to detect and clean all viruses it saw and that could have infected the computer. We think it could be better as it allows people to receive and forward malware without any warning, which would be better for the community. But for the user, what is important is they are protected from infecting their computer and MSE does that well.

CA (Computer Associates anti-virus/anti-spyware) performed very well. It did miss a couple of viruses at the start. We know that all virus manufacturers take up to 48 hours to release new signature files so this is expected behaviour, although not ideal. The ideal is there be no delay, but that is not possible. Once CA had released the new signature files it then had a perfect score, even finding a malware which whilst benign, was not found by others.

OzEfilter takes a different approach in it helps users delete emails at the mail server before the malware even reaches the computer. OzEfilter did let the benign email through, but that is because we want to receive emails from the mail server so we can receive emails which bounced because of email addresses which no longer exist. The mail server really shouldn't be passing the email on because it isn't an email it generated. OzEfilter also stops spam and other forms of malicious emails such as phishing attempts from reaching a computer. Using OzEfilter and MSE would be a very good option. Using OzEfilter with any of the anti-virus software package would reduce the chances of a malware infection to very low.

This face-off however was about the free anti-virus software packages. To the victor which in this case was Microsoft Security Essentials goes the trophy and our congratulations.

If should be noted that no one knows how any of the anti-virus packages will perform with new malware packages. All we can say is for the malware received over the past week, MSE performed best.

The free anti-virus face-off is now over. In the future if there is interest I would be happy to have a face-off with the leading commercial anti-virus packages. In this face-off we would see how CA (Computer Associates) matches up to Norton anti-virus 2010, Trend Micro 2009 and McAfee. Now that would be an interesting face-off.

I hope you've enjoyed the face-off and it helps you make better decisions as to which anti-virus program you use so your computer remains a joy to use.

Round 4 - Free Anti-virus face-off. Free AVG vs Avast Free vs Microsoft Security Essentials.

Today there were quite a few more nasties arriving than usual. There was some unusual activity which I'll explain later.

The following are the unique malware received since yesterday.

The unusual activity was with the following malware.

Mail delivery failed : returning message to sender / Message Part>

MSE did not detect the virus because it was text in the message. Because it was text it couldn't be downloaded as a file. Avast picked it up and tried to delete it, but it didn't delete and Avast kept trying each time we clicked on the message. AVG missed the malware. CA identified and fixed the malware. OzEfilter also missed the malware.

The reason the anti-virus products missed this malware is it wasn't an attachment, but it was text which would have been the raw form of the original data. This form is usually not seen by the use. It took us a while to work out what had happened. I'll explain.

Somewhere a computer sent out a fake email with malware using our domain. The receiving email server saw the malware and sent a copy of the malware as text in an email message to the mail server I use, thinking it was that mail server that sent the message. My mail server saw this rejection of the message and passed it back to me. Now since I send out emails to people on my mailing list and sometimes people's email addresses no longer exist, I need to accept these emails from the mail server. I could just delete them, but this information helps me to keep my mailing list clean. That is why OzEfilter didn't flag the email. It was from the mail server and I want those emails. MSE had nothing to work since it was text in an email and not an attachment. AVG missed it, Avast saw it and got stuck on how to handle it. Only CA treated it correctly. Although since the virus was now in the form of a text message as raw data, there is no way the virus could infect a computer. Thus, whilst this was very interesting the analyse, from a users point of view it would have been a benign email that was just junk to be deleted.

OzEfilter works differently to other approaches. I set the conditions so OzEfilter knows who I receive emails from and then it only shows me the emails from people I don't know. This approach is called exception handling and saves quite a bit of time. I only need to review the emails from people I don't know before accepting them or not. Emails from people I now I always want to accept. I am presented with a screen which shows the total number of emails and how many emails are from people I don't know (the To filter value on the screen image belowe). Most emails from people I don't know are spam or malware. I receive 70-100 emails a day and around half are unwanted. All of the unwanted emails are deleted at the mail server and never reach my computer. When I review the emails I see the subject, who the message is from, and around half the time I see the country the email has come from. The country of origin is a great indicator as to whether or not the email will be wanted.


CA missed 0

AVG missed 1

MSE missed 1

OzEfilter missed 1

Avast missed 2

One other thing that I noticed was the MSE signature file had not been updated since the 6/10 and it was now the 9th of October. Before checking for malware I perform an update of all the packages. However in the real world this would not be the case. The user would turn their computer on and within a few minutes check their email. If an update had occurred then the software would have the latest protection. If not the users protection reduces. The next round will be done without manual updating.

Another thing that MSE did that was strange is when I went to save to the computer MSE stopped me. That means MSE does recognise some malware in a zip file. This isn't what I've seen before.

For MSE to be a better product in my opinion it should automatically check zip files without the files being extracted. Microsoft should at least have their own products (Outlook, Winmail, Outlook Express) check the attachments on incoming emails as they arrive. That would in my opinion put MSE ahead of the pack.

AVG performed very well today. It placed malware into a separate folder without fuss.

Avast has been slow recognising the malware others now recognise. One thing I didn't like about Avast is when receiving emails it would stop if it found malware and wait until I took action. With dozens of malware that was quite time consuming. With the other anti-virus software I could leave the computer and do others things. I had to interact with Avast and it was quite time consuming and tedious.


1. CA
2. OzEfilter, AVG, MSE
3. Avast

The winner of today's round is CA. That's a pretty impressive effort from the CA team. At this stage CA is out front because it is having the best outcome and scans email attachments as they are received.

Until tomorrow.

Round 3 - Free Anti-virus face-off. Free AVG vs Avast Free vs Microsoft Security Essentials.

Ready to face another day, AVG, Avast, CA, MSE and OzEfilter have had a good rest. The combatants today face the following enemies.

All the combatants except Avast had a good day.

CA missed 0

AVG missed 0

MSE missed 0

Avast missed 2

OzEfilter missed 0.

I did notice with CA that somewhere between around 8:07pm and 10:24pm last night the anti-virus software updated and malware it didn't previously find in round 2, it now found and removed.

CA removes the malware in the email and provides a text attachment letting the user know the malware was been removed.

AVG puts malware into a separate folder which is a pretty neat way of handling malware.

Avast removes some malware and provides a notice in the email, but for others as the email comes in it asks if you want to block them. Then later when you click on the email it asks if you want to delete the email. I thought this was an extra and unnecessary step. The sound file is certainly a good warning to users, of course, if you receive too many emails with malware the warnings could become annoying.

MSE whilst is has shown to be the best at finding malware with a perfect score so far, the problem is you receive the emails with the malware attached but don't know. You can send the malware on to others and wouldn't know. You can save the files to your hard disk and you wouldn't know they contained malware. It is only when you save the attachment to your computer and then extract the malware file from the zip file that MSE takes action. I can't complain about the action because it is certainly working. If you can work this way then MSE is a good product.

OzEfilter works for me. I wrote the program. It allows me to check my mail at the mail server and delete unwanted emails at the mail server before they ever reach my computer. I receive 50-100 emails a day and half of those are spam and malware. OzEfilter helps me to delete spam and malware so I never receive the emails. OzEfilter isn't an anti-virus program and you should still install an anti-virus/anti-spyware program in case you receive a malware infected email. Using MSE and OzEfilter together would provide an excellent solution to my needs and probably the needs of many people who use pop based email accounts. OzEfilter doesn't help if you are using web mail.

For those just using web mail, MSE could be a good solution as it will detect and remove any malware you download and so far it has been 100% in its detection.

AVG, Avast and CA have all missed malware. AVG and Avast are free for personal use. MSE is free for personal and business use. CA is a commercial product. In this round CA pulled ahead of Avast, but so far there hasn't been much difference between AVG, Avast and CA.

This round has also shown it can take a up to 48 hour for the anti-virus software developers to update their software for the latest threats.

Outcome for round 3.

1. CA, AVG, MSE, OzEfilter
2. Avast

Overall today has been a very good outcome for the combatants. Four with perfect scores and with Avast only missing two. Except for MSE not being integrated with the email client, MSE would be a clear leader at this point in time. That is pretty impressive. Only the future will tell if MSE stays in the number one position.

OzEfilter has performed to expectation. It isn't an anti-virus program, but more a helper to help stop unwanted emails before they reach your inbox. So far it would have stopped all of the unwanted emails from reaching your computer.

CA, Avast and AVG have all let malware into the computer and whilst they perform pretty well, letting email with malware into a computer will result in infections. It is only a matter of when, not if.

Use the Energy Cost Calculator to save money on power bills?

I'm quite excited about three new items I have available as we are now all very aware of how important it is to save energy. Two of the items I've already purchased myself and the third I'll be purchasing shortly. To me the best recommendation for a product you can get is from someone who uses the product.

The first product is an energy meter which enables you to get a reasonable idea of the watts an appliance uses.

Lights are easy because the wattage is written on them. However for many of the appliances around the home the best way to get a an idea of the energy they use, is to measure their energy use. I've found some very interesting results. Once you measure how much energy an appliance uses, you can determine the best approach to saving money. (Whilst the power meter has other functions, I only use it to measure the watts.)

The second item is a four port power board with a remote control. This item allows you to turn off the individual pieces of equipment plugged into the power board.

For example, I've found a TV plus a DVD when in standby consumes around 25W. That adds up to about $38 a year if the item is left in standby and never used.

My aim is to use the four port power board with the TV/DVD/Entertainment system. I can power down all the devices, or if I want to record something on the DVD recorder, I can leave that powered on. My father-in-law uses this unit with his computer so he can power down his computer, monitor, printer and ADSL modem without having to get under the desk.

The last and I think the most exciting item is the remote control with three power packs. (I call them power packs.) You can plug the power packs in different places around the home and power each unit on or off separately as you go around the house. (I get a feeling I'll end up buying two of these so I can use them with the computers as well.)

For example you can power off the TV/DVDs you have in different locations around the home. For me the payback for power packs will be around four months. There isn't many things you can buy which pay for themselves in just four months.

To help everyone work out the energy cost of an appliance over a year I wrote an Energy Cost Calculator. You can use the calculator in two ways.

1. To find the energy cost for an appliance over a year.

All you need to enter is the watts the appliance uses and the amount of time per day the appliance is on for. Hit Submit and you'll get how much the appliance costs a year.

2. To find the payback period.

A really handy feature of the calculator is when you are trying to work out if it is better to keep the old inefficient light, or to purchase that more expensive low energy light. I wrote the payback feature because whilst it felt good about purchasing the low energy lights, they are much dearer than normal lights and I wanted to know the payback period.

As an example I was looking at replacing two 40W normal screw in globes with two 8W low energy globes. The 8W globes were expensive at around $7. Price varies quite a bit from store to store. The good thing is if you look around, often you will find specials. I picked up two low energy globes for $9 for the pair on special. 

Using the Energy Cost Calculator I entered the two globes as one to give 80W for the old globes and 16W for the new globes. I estimated the light was on for around two hours a day. It could be more, but this is a good estimate. The calculator showed me the payback period would be 13 months. Since I expect the globes to last three years or more, after the first year I'm saving money. To keep using the old globes doesn't make sense.  

  1. Check around for the price of globes as you do your normal shopping. You'll find the price can vary quite a bit from store to store.

  2. Work out what you want and then take your time to buy. I find there are often specials on lights.

  3. Think about how you use your lights. A small change of habit can save money without replacing any lights. You may change some lights now that you use more often and that gives you the biggest saving.

  4. Don't assume the energy a device will use. We've been very surprised by how little energy some devices use and how much others use. The best decisions are made based on real knowledge. The power meter has helped us make better decisions. I could say knowledge is power, but in this case, less power.

If you are interested in purchasing any of the above devices please feel free to contact me. I can organise shipping anywhere in Australia. You can find the pricing on the Electronic Cost Calculator and if you click on the image on that page you can see a larger image.

Round 2 - Free Anti-virus face-off. Free AVG vs Avast Free vs Microsoft Security Essentials.

Round 2 of the anti-virus face-off didn't go as expected. I found the issue with emails where the emails weren't kept on the server for all the computers to retrieve. Completely my fault. I have multiple email accounts and one of those accounts would clear the server. All though is not lost. The challenge continues.

For this round I retrieved all the emails using the computer with CA installed. For the emails containing malware that CA did not detect, I forwarded them on to all the other computers. In addition instead of listing every malware infected email, I've decided to list only the unique emails.

The following are the emails received:


Jessica would like to be your friend on hi5! / Invitation
You have received A Hallmark E-Card! /
Stolen document /
Shipping update for your order 254-78546325-658742 / Shipping
Re: Re: website /
Canada immigration / winmail.dat>Documents and Settings\MyDocuments\Readme.doc .exe
Error /


Total unique malware 7

CA missed 3


Because the emails were collected it is not possible to see if the other combatants would have missed malware CA detected. All we can now do is check to see if the three malware missed by CA were handled by the others.

AVG missed 3


Avast missed 3


MSE missed 0

OzEfilter. Would have deleted the emails at the mail server.

Outcome for round 2.

1. MSE
2 AVG, Avast, CA

What is interesting is AVG, Avast and CA all missed detecting the same files that were missed from yesterday's round. It will be interesting to watch the time it takes before these products correctly handle the three malware.

MSE already handled them so the real challenge for MSE is to see what happens when it receives malware it doesn't already know about. Time will tell how it performs.

Free Anti-virus faceoff. Free AVG vs Avast Free vs Microsoft Security Essentials.

Our aim: To pit the free ant-virus products against each other in a gruelling, ferocious, winner takes all battle.

Our technique: To drag out three old warriors consisting of Windows XP SP2 computers with Outlook 2003 installed. They may be dated to some, but to others they are skilled operators.

The outcome: Over the coming week as the warriors do battle, I'll report how the battle unfolds.

Warrior 1: In the first corner we have AVG Free. Well known and mentioned in the inner geek circles.
Warrior 2: Avast Free version. Less well know, but still a very brave warrior.
Warrior 3: Microsoft Security Essentials. The new kid on the block. Will MSE get its block knocked off, or will MSE be the new David.

We don't know the outcome. No behind the scenes deals have been done. What you read is the combat as it unfolds.

Join me on this journey of evaluation. To see what we will see. Enjoy the ride because it will be over all too soon.

Let the journey begin......

The rules of engagement:

1. All combatants will pit their skills against the emails being received. These emails can hold nasties unimaginable. Those weak of heart should avoid reading further. The nasties the combatants have to beat are emails carrying malicious loads. Combatants do not have to pursue links outside of the arena (such as clicking on links), but only fight the fight brought to them.

2. At the end of each round a score card will be presented. It is expected each combatant will receive minor blows, but none are expected to be fatal.

3. A side event will be running in parallel. A little know outsider named OzEfilter, often seen working with a combatant, will be watched. OzEfilter is like a shield for a combatant. OzEfilter fends off the enemy before ever reaching the combatant. But should an enemy get past OzEfilter, the combatant needs to be able to slay the enemy. OzEfilter however has proven to be so effective in many cases, combatants often live a life unaware of enemies.

To the victor goes the spoils.

Round 1: 6 October 2009

The combatants trusty steeds were tended too. Each steed consisting of a Windows XP SP2 computer. Outlook 2003 installed. AVG free and Avast installed easily. MSE's steed was older than the rest and had to be upgraded to XP SP2. Only then could MSE mount and begin the battle. All the combatants prepared, the battle begins. In waiting, 150 plus recent emails, most friendly, but some containing enemies disguised to trick.

Avast was the first. As each email was received, enemies were loudly announced and lay to rest. Avast is not shy at letting the crowd know it is doing battle.

AVG was next. The emails were received silently. Nothing was said. The enemies were captured and put into a separate folder.

MSE welcomed all visitors into the inbox with no fanfare. One by one the emailed visitors were invited into the local computer. One by one MSE slay the enemies and partied with friends.

OzEfilter: The combatants shield. Not to be used without a fellow combatant, but providing extra protection to the combatant. A combatant generally end up doing little as OzEfilter, the trusty friend, deals with many enemies from afar, before they even approach.

CA: An employee of the kingdom, paid to do what others do for free. Is CA worth his weight in gold? We will see.

This test was going well. The first computer with CA received the emails and the result was the following:

CA missed 5


AVG missed 5

Avast missed 3


MSE missed 0

Unfortunately something happened such that all the emails on the server were gone before I could perform the receive of emails. Instead I forwarded on all the files CA missed. MSE doesn't check at the time of receiving an email. It checks when you go to save the file to your computer. In the case of a zip file it doesn't check until you extract the files. At this point MSE identifies the file and then takes some time to remove the file. MSE correctly identified all the files as malware.


Because the emails had been received and removed from the mail server, I could not test OzEfilter, so I had to desk check manually what would have happened. OzEfilter shows a list of emails from people you don't know. You can then review those emails and delete them at the mail server before they ever reach your computer. In this case all emails were from addresses we don't already know and accept. So all viruses would have been deleted before reaching the computer.

Outcome for round 1 

1. MSE
2. Avast
3. AVG
4. CA

With round 1 over the combatants can earn a well deserved rest. Tomorrow is another day, another fight.

Until then.

Search Australia now available as a Firefox 3 search engine.

The Search Australia page is proving popular with Internet Explorer users. Now the page can be added as a search engine to Firefox as well. Click on the link at the bottom of the Search Australia page and you can make the page your default search engine.

Now you can have your home page as your preferred page instead of the Google page and you can use the search area in the top right of Firefox to perform your searches.

I've found many people don't realise the search area in the top right of modern browsers is available until it is pointed out by someone. Once you know it is there however, searching becomes a lot more fun because you can add a number of search engines. If you want to check out what you can do with search check out my Fun With Search page.

Goggle it - Search only Australian sites.

If you want to do a search using Google and only search Australian sites, try our Search Australia page. This page uses the Google search engine and limits the results returned to only those sites considered to be associated with Australia.

The sites associated with Australia are the domains ending in .au.

Previously I used Pages From Australia in Google but now I don't find that limits pages to Australia. By limiting the sites to sites with domains ending in .au you don't end up with large overseas organisations with deep pockets promoting themselves at the expense of smaller Australian organisations.
Please enjoy.

Virus alert: Subject: ALERT. Attachment:

As part of my review of Microsoft Security Essentials yesterday one malware attachment was not picked up as malware by any of the software packages I was reviewing. That is AVG (free), Microsoft Security Essentials or CA Internet Security Suite Plus 2009 all could not identify the attachment as being malware.

The email had the subject "ALERT" and the attachment

This attachment has now been confirmed as malware.

You should delete any of these emails that you receive. Do not extract the contents of the zip file.

Virus: Microsoft Security Essentials gets the thumbs down and thumbs up.

To my surprise I've completed the parallel testing of Microsoft Security Essentials in a much shorter time than I expected. I have sufficient information now on whether or not to recommend Microsoft Security Essentials to my clients.

I have read a review giving Microsoft Security Essentials 9 out of 10. It is pretty obvious to me at least, insufficient testing of the software was performed. All I had to do was to collect one days worth of emails, compare the results and that was sufficient to reveal all I needed to know.

I am hopeful that Microsoft uses the feedback from its user base as they could have a great product in the near future. Full marks to Microsoft for getting this far with their product.

If you are interested in my results they can be purchased for $9.90 from MyAnswers. You can find the solution on the Virus page of MyAnswers. The solution number is 1931.

PS. Based on the Free Anti-virus face-off results Microsoft Security Essentials performed best of the free anti-virus solutions tested. It really is about how you use MSE and what you are happy with whether you consider MSE to get the thumbs up, or the thumbs down. In my opinion it gets both. To use being able to forward on emails to other with malware attached isn't community friendly. But to protect your own computer, MSE performed very well.

Microsoft Security Essentials: I feel naked and exposed, but all for a good cause.

Microsoft have released their free anti-virus software Microsoft Security Essentials. The current players in the market will use the old argument "you pay for what you get". But the reality is we've tested the leading anti-virus software packages that are generally available to consumers from retailers and we have to say we've been disappointed in all of them.

Is Microsoft Security Essentials good enough?

I support a lot of customers and for my own needs the question for me is: Is Microsoft Security Essentials better than what I'm currently using?" Should I stop paying my yearly subscription and move to Microsoft Security Essentials and save some money.

I decided the only way to answer this was to get naked and exposed, in a virtual sense. That is I disabled the anti-virus software on one of the mail servers, so I will now receive all potential malware threats that are sent to me. I receive the same emails into two different computers. One running Outlook and my current anti-virus software, the other running Outlook Express and Microsoft Security Essentials. The email client isn't important in this test. What is important is how each anti-virus product performs.

I've already received one email with malware attached and I can say the result totally surprised me.

Over the next week or so I will be evaluating Microsoft Security Essentials with the best approach I know how. That is a parallel test of two anti-virus software packages receiving the same emails and noting how they respond to malware.

If you are using other leading anti-virus software packages, I can assure you in many cases they won't catch the very latest malware. You are exposed. Is Microsoft Security Essentials any better? I hope to find out and share the information with clients. The result could be savings of thousands of dollars for those who know me.

If you are interested in my findings, I'll be posting the results in MyAnswers and update the MyAnswers solution as I find information to share. As I said, I am already surprised with the outcome and that's only with the first infected email I received.

I am also happy to parallel test Trend, Norton and McAfee and other anti-virus software if there is interest with paid support.

I would highly suggest that if you look after computer users, you also review Microsoft Security Essentials for yourself. Most of what you read in the media is without substance. The protection the anti-virus software companies say they provide is misleading, because the biggest threat is when you have anti-virus installed, are new viruses and in that area all the anti-virus software packages tend to perform poorly. 

If you are a computer user, the best thing you can do to protect yourself, is to learn some safe computing techniques as well as using anti-virus software. Using the low cost techniques I use to protect myself from malicious emails, I rarely receive email based malware into my computer.

So whilst I feel naked and exposed, I know it is a for a good cause. My customers will end up with the better outcome and for me that is worthwhile.
