If your computer becomes infected by a newer breed of virus,it can be used by someone in a remote location to control other computers and your bank account information, credit card numbers and secure passwords can be stolen.

Symantec, the company that offers the popular Norton Anti-virus software, is compatible with Vista and offers a free 90 day trial for new users. They also offer a complete security package that offers all of the protection of the original antivirus software, in addition to identity theft protection and a two way firewall that prevents outside access to your computer.
Trend Micro is not as well known as Symantec, but they offer much they same software packages as their larger competitor and were recognized as the top security vendor at the CIO Insight. The Trend Micro Internet Security package comes with a 90 day free trial, but the stand alone anti-virus software only comes with a 30 day trial period.
Kapersky Anti-Virus 6.0 has recently been reconfigured to work with Windows Vista as well. It provides good anti-virus protection, but there isn't a trial period.

Kapersky was named a CNet Editors' Choice and a best buy from Computer Shopper magazine.
