Same thing happened to me...
My girlfriend found pics of women's asses that I took, and some fart videos. Just like that guy said, she's cool with it when she's in the mood, but when she's a bitch, I become this disgusting pervert pig. We made up after arguing, and I don't get as much love from her as I did in the past. Sucks when they find your stash!!! Every night before I shut down the computer, I make sure all internet traces are deleted, and cleaned up. I have a folder where I keep my stuff, which is "hidden." I also make sure to delete the contents of recent items, yet she STILL found recent photos that I was viewing?
How can I delete the folder of "recent photos and videos" in Vista? Just when you think you're 100% in the clear, she finds shit!!!
