I just hooked up a computer that my dad got from his work. There was a few problems with it and the guy that used it at his work was a moron when it came to using computers. I was wondering if any one knew of a free program that would scan the computer for any problems like viruses or adware/ spyware. I dont really want to go out and buy the software for a computer that i got for free that isnt even that close to top of the line....
