NO! Not avg! Not yet! Get the new Kaspersky anti-virus version 7.0. It comes with all features and a new Heuristic analyzer. It's excellent. I killed all the trojans on my pc. So go kaserpsky first then go avg. That's my plan =p (Btw kaspersky is a 30day trial but it's really worth it to buy. But i'm poor so going avg after my trial is over)
