Well, I thought I would try the Microsoft Security Essentials. Downloaded it yesterday, had a heck of a time uninstalling the AVG. Anyway, I have a lot less processes running and so far things are smoother and faster. So far, so good. Also got the new IE 8, that seems to work better also.
The best way to uninstall software is to download Revo Uninstaller. It is a free download and it goes above and beyond Windows normal uninstall, it searches for extra files left over and it quite surprising how much it finds sometimes.
