As noted above, *nix is the answer - on Windows, try:

Spybot S&D - trojans
AVG - virus
Sunbelt Kerio Personal Firewall

All have free personal versions.

you should consider the consequences of a system failure and balance this against what it costs annually for something likeNorton System Works.

If you've ever worked in the support industry, you'll quickly realize that Norton's products are the cause of the "problems" they detect ;)
