Try that one, it is free from the Internet. It is working fine with my windows xp service pack 3. You could always use any other antivirus software, let me just remind you though, that you need to use only one software, since using two or three antivirus software would really slow down your computer...
Avast!
you decide by features,free, or bought.If you want warranty,tech support backup, do you get that with freebies? Me i use Norton's 2007, can't complain,buy 12 month subscription over net, super tech support.
