I Disagree, McAfee isn't a resource hog on my upstairs comps nor my laptops.... The Max RAM i've noticed it use is about 15k and thats while i was scanning. and I refuse to install AVG because i hate it. I don't like one bit of it, Avast and Avira i've never heard of till you two brought it up. However i have heard of NOD32 and never used it, ZoneAlarm isn't a good suite because ZoneAlarm blocks the internet on the newer versions till you do something to unblock it from doing it. I read it in this computer mag my dad had that and Norton 360 is a big pile of rubbish. It is not as integrated as Mc Afee, Drive Sentry or any other anti-virus software out there. It has been proven by technical experts and was released somewhere i think it was a website or a mag again i saw lol.
