Active Virus protection will slow down your computer. The big box programs like Norton and McAfee a famous for being exceptionally a slow down problem. Try a simpler Virus scanner without the bloated security center bundled with the big box programs.

AVG has a good personal use Anti-Virus product available at: http://free.grisoft.com

Avast Antivirus, also for non-commercial use is available at: http://www.avast.com/eng/avast_4_home.ht...

Both these products include active background scanning modules!

Bitdefender has an excellent scanner and removal tool but does not have any active background protection in the free version that is available at: http://www.bitdefender.com/site/Main/vie...

Antivirus software can slow down your computer a little bit but if its more serious than that than you need to put some spy wear scanners and scan for spywear because spywear will slow down your computer .Windows has a new free spywear scanner called windows defender.If your computer is windows it will work great.Dont forget also you need to clean your internet fills out to got to control panel, than clean disc space ect.
Maybe you just need some more memory.
get kaspersky anti-virus 6.0, it's the best that works for me.
