Hello. Can you guys tell me some info about Avast! and Antivir. I want know which have better: -detection rate -better heuteristic -definition number of viruses, worms, backdoors etc (now Avira have 745.000, what about Avast?) I don't need things like adware scaner or http scaner (i'm using safe browser - not IE , and Spybot S&D for adware). All what i need is good software against viruses, trojans, worms and keyloggers. I know also after last update to Antivir has beed added rootkit scanner and e-mail protection. Thanks for helping me . P.S. Sorry for my poor English, don't flame me please... .
