I recently had to reformat a friend's PC. He fucked it all up. Anyway, I ran Spybot first, and came up with over 2700. Then Ad-aware still came up with over 250. Plus his PC had a virus(s), and he had no virus protection on his PC. So to teach him a lesson I reformatted without backing anything up. He lost about 45 gigs of MP3's and porn.
