I'm sure there is all kinds of junk in there….I would like to fix this computer, clean it up and basically use it minimally. It has been run through the works and was a general purpose computer and had alot of carp** on it. Please help! I go a warning that I got some kind of spyware, ran Spybot, got a million hits, then my computer started randomly turning off. It would give a 1 minute warning, and count down and shut down. Also, 50% of the time I navigate to a different webpage (whatever page does not matter) and IE just shuts down completely and I get an error message. Thanks for the help!
