AVG www.grisoft.com has one of the best

go on the computer put in free downloads and they have some or if you use lime wire you can but I'm not sure if i would trust it with no protection if you use msn they have it free you just install it
have used AVG Anti Virus, Zone Alarm Firewall, Spy-bot Search and Destroy and Ad Aware both spyware killers for years. They are all free for personal use and I have had no trouble with Viruses Trojans etc. AVG does not slow the system down as much as some other products and Zone Alarm allows a lot of personal configuration unlike the Windows Firewall. They can all be downloaded from the following link. http://www.computeractive.co.uk/ On the home page select downloads and then the appropriate category.I also use Windows Defender from the Microsoft site. It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. Hope this helps.
This is the best (and SAFEST) site i've found for lots of great freebies - including AVG Free and other spyware programs: http://www.filehippo.com/
