Antivirus Software – Get The Bugs Before They Get You!


By Felicity Walker

You turn on your computer, and it doesn't look quite right. Maybe your icons have changed, or the background picture is wrong. Some options are disabled. Even worse, you may not be able to boot your computer up at all. Guess what – it's probably got a virus.

In today's online world, protecting your computer from all the nasty things online is vital. Viruses can cause obvious issues, as described above, but they can also run silently in the background, propagating themselves across your computer and transferring on to the computers of people you know. Mostly, you only know you have a virus when substantial damage has already been done.

Some common signs of a virus include:

•  Programs working erratically

•  Computer locks up

•  Greyed out options

•  The browser home page has changed

•  Icons have changed

•  Difficulties starting up the computer


There is a solution! Antivirus software is readily available, and the good ones are very efficient at dealing with viruses in all their many and varied mutations. Basically, if you're online, you need this type of software.

So which one do you choose? For starters, be careful of using something free off the internet, particularly if it's one you've never heard of. Sometimes these programs are a way of implanting more viruses on your computer. Some of the better known brands give you the option of doing a free scan online, which is useful, but not a long term solution.

It's really important to choose well-known antivirus software. Ask friends, or someone computer savvy, for their recommendations. It may be worth visiting a computer store and buying it there, rather than online – after all, if they've gone to the trouble of stocking it, it's most likely an established and trusted product.

There are plenty of good brands available, far too numerous to list here, but some of the best known are from McAfee, Norton and Trend. Check out the support available to you – can you contact someone if you have trouble installing the software?

Most importantly, make sure there's an easy way to update the software on a regular basis (preferably as part of the purchase cost!). For example, my antivirus software pops up a little box every time an upgrade is available. I click okay, and it's automatically downloaded to my computer. Viruses change and develop at an alarming rate, so it's vital to keep your antivirus software up to date.

Finally, the all-important backup! The word “backup” tends to produce the same glassy eyed response as the word “budget”, but it really is an essential part of being online. Regularly backup your important files to CD or DVD. If you're a business user, an automated and frequent backup process is vital. Once a virus has destroyed your computer, it's too late.

Being online is wonderful, but don't let it become a nightmare. Antivirus software will play a vital role in keeping your online experience a positive one.

Anti-virus software is used to find, remove or fix files that are infected with computer viruses. Most anti-virus companies release weekly updates of their databases to help keep you safe. Your anti-virus software uses these weekly updates (also known as virus signatures or definitions file) to identify newly discovered viruses.

The most basic anti-virus programs normally have several features to it, the memory resident scan, the system or file scan, and an automated updater. Many more sophisticated programs have many other integration tools that loan in to your instant messengers, your e-mail software and many other programs.

It's very important when you configure your anti-virus software to always make sure you can download new updates every week, if you scan your system for viruses, and your definitions file is out of date it may not even find a problem with your system. Additionally, you should make sure you do in fact scan your system on a regular basis. I personally set my computer to scan around 4 AM so it doesn't bother me.

When you download software, e-mail attachments, or introduce new media (diskettes, cd's, jump drives) in to your system you should scan them before running or viewing them inside another application.

Deciding on which program to use often causes people a lot of head aches. Some anti-virus programs require you to pay each year for a subscription to their virus databases so you can keep your system up to date, others are just expensive out of the box. Additionally, which tends to be the biggest factor in my decision making, is how much resources does the program use.

My favorite anti-virus program for the past couple of years is AVG Anti-Virus, by GriSoft. It's totally free for the personal edition and the updates as well. It has all the major features expected out of an anti-virus suite and is really simple to use and setup.
