I don't really care about old viruses, or how much an antivirus can "catch" in those test, the most important thing is being able to stop an outbreak (that can do serious damage) a.s.a.p....
I can't afford buying programs like norton, I've tried 3 free antivirii avg, antivir , avast.... Avast uses the most memory ( I hate that but it seem 4.7 uses ~10mb less RAM than 4.6) Again n again, avast offers the best update, the only true incremental update, Antivir 7 recently added incremental update but still so much inferior, the updates will be as big as 500k, or 1 MB alternate days.....kinda burden for 56k modem users
RejZoR, I find anitivr heuristic very annoying, so many malwares warnings if set to high
