i use avg anti-virus and anti-spyware i also use the rootkit scanner and i have not had a problem with them. I mainly like them because they use less system resources then most other anit programs.

AVG is free %26 so is Skybot. Too much anti virus will slow your computer down. You don't need more than two.
Best available free antivirus is AVG

I use to use AVAST.
AGV Anti-Virus is reasonable but if you pay for an antivirus program you can get better
I always use and trust avast! anti virus. Its free to keep you protected!
