I just now got to reading this thread... Anyway... as a Guinea Pig for testing software for my mans work (they sell AVG and CounterSpy, the best US reseller on the East Coast), I know alot of programs that work and alot that are crap. Crap Cleaner sucks... I won't even go into the story about how it made my OS crash... I haven't used CleanUp... maybe I'll point that out to Robert when he gets here. Adaware really sucks... often leaves things behind, much like Norton. Microsoft AntiSpyware/ Windows Live One Care... sucks... got 13 worms using this stuff. Not including all the cookies and trojan viruses I got. SpyBot is good. We use this when we clean up someone's machine. Very good product, in my opinion!! Spy Sweeper: Have not tried it Ewido: Great news!! Gristsoft came out with a free version of Ewido!! This is also a great product, Paired with AVG Free, you can't go wrong! Avast uses up alot of memory, thus making your computer suer slow, and misses things as well. AVG Anti-Virus Free Edition: Great product. Though I have a paid version, I know many people that use AVG Free, and are very pleased with it! And as for FireFox, I LOVE IT!!! The tabbed browsing is very handy! There are lots of other reasons I love it, but I can't remember them at the moment!
