I may not have the latest i7 processor, but I do have a respectable quad core that I regularly load several duties including phone, cable DVR, banking/shopping, HD movie editing/authoring, and many more, and it takes it all without a hiccup!

I don't know where people get this "memory hog" stuff about Avast - it uses WAY less resources that over half of the stuff out there, and definitely scores that way in the top five. I've NEVER been let down by Avast! I would probably prefer ESET, but since 95% of my clients can't afford paid security products, I decided I needed to take the same risk as they do - only I don't see the risk side of it yet. In over 5 years I've never had a major breech in my honey pot lab.

Hell - IE9 stops 85% of the ZERO day threats I test with now!!
