Still so much to learn for you Samker ; ))
But seriously: explain why not. There is not a good reason. And all my friends that listen to my combo-advises, stay virus free. For real. So... What else is there to want? Speed? Avast is one of the leanest AV's!
No Karma this time :> But Peace! non the less,

Avast is great. I have been using this AV on win xp, vista, win 7 (32bit/64bit). Not a resource hogger compared to other AV solutions. Avast also has free home edition and works very well. No av solution is 100% but keeping your computer patched up will great assist.
