Need some help. New girl friend is moving in temporary. She is very,very good with computers. I'm not, but I'm learning, I'm a aircraft mechanic. Problem, I don't want her to see the history on my computer. Web sights visited ( I used web. sights to met other ladies). Also I don't want her to find history of my e-mails and photo's my ex-girlfriends have sent. I believe what I've done in the past on my PC is none of her, or anyone's concern. She will be using my PC. Running Windows XP. I down loaded CCleaner does it work? I care very much for her fillings. If need be, I'll install a new a drive and trash this one. Thanks very much for the help.
