While firewalls do a good job of detecting and preventing attempts to attack or gain access to your system, they are not a substitute for antivirus software.

Antivirus software is still a vital tool in protecting your computer and should be used in conjunction with a firewall to maximise your protection.

There are many antivirus software packages on the market and most computer shops will stock them. Below is a list of some of the available packages:

AVG Free Edition - requires Windows 95 / 98 / NT4 / Me / 2000 / XP
