Preventing Computer Viruses and Trojans

Worms, Trojans, Spyware etc., are malicious pieces of computer code (short programs) that can infect your computer.

For all infections the "pay load" - the damage they do - can vary from changing the 'home page' of Internet Explorer or slowing your system down; to rendering the computer almost unworkable or bringing down the office network. Some are designed to capture sensitive information by logging all your keyboard activity including pass words or 'screen grabbing' and pass the sensitive information on to fraudsters through the Internet. The latest generation of Internet worms can leave your computer wide open to others so that personal and financial information is not safe. Some viruses allow others to take control of your machine and use it to send out ‘Spam’, without you knowing that this is happening.

For further information see "threats".

Avoiding Becoming Infected

Avoiding becoming infected requires a combination of prudent behaviour AND Software tools to protect your systems. Prudent behaviour alone is not sufficient to stop infections. Can you rely on your staff, or other people who use your computer to be careful? Likewise, a friend or colleague may have innocently forwarded an infected e-mail to you. This is why it is important to use suitable anti-virus programs and other packages as well.

strongly recommend AVG Anti-Virus, which uses revolutionary technology to ensure complete and efficient virus detection. It has never, in our experience, conflicted with hardware or software installed on computers; the same cannot be said of some well known brands of anti-virus software.

On the contrary we have on many occasions had to attend to systems which were experiencing problems such as running slow. Upon uninstalling the well known brand of anti-virus and replacing it with AVG, the problems ceased!

Anti-Spyware as well -What is more, this product provides security protection against spyware, adware and other malicious programs.

Firewall

For further protection for your system, and preventing intrusion, you need to consider a firewall. This is especially true if your system is connected via broadband. AVG antivirus plus firewall is the product which we recommend.

AVG Internet Security

This is the ultimate in complete protection for your systems, including:

• Anti-Virus
• Anti-Spyware
• Anti-Spam
• Web Shield*
• Firewall

*"Web Shield" protects against malicious websites which might harbour Trojans.
