If you have original win XP you can download Anti Virus from Microsoft.com namely, Computer associates(eTrust AV, 1 yr subscription), Norton 2006 , panda and McAfee(all others 90 days). These are free subscription downloads for Microsoft users.

ZoneLabs is pretty good, it is a complete security suite i,e with firewall, AV, privacy and anti spyware.

Go for AVG Antivirus or Avast! both are free, well supported, and much easier on your computer than norton.
GO TO: http://www.trendmicro.com

IT'S FREE !!! This is what I use when Norton Can't Seem to do the trick.

Big Companies like http://www.stream.com use this tool!
If you happen to be a AT%26T Yahoo branded DSL service subscriber, you'd get the anti-virus software for free. I am pretty happy with the software they provided. It came from CA (compute associates), named EZ something.
Good two and affordable :-
