OH MY GOD IT'S JAWS!
Avast. I have it and it's free. It blocked 5 Trojans yesterday beca... Nevermind. ^^' Anyway, I recommend to get Avast. It's the best
Get AVG.
I must say Avira... :P
I just use System Restore whenever I get a virus. I have administrative properties, ya see.
Avast.I don't like Avira's interface, and AVG's recent version isn't very stability.
