I let a friend of mine borrow my new computer for a week and when I got it back Norton Anti-Virus said there was a 2 problems and it hasn't been working right since. I checked the history but it had been cleared and he had installed limewire. Someone told me there was a way to check files even though they had been deleted, like they are still on the hard drive. I don't know if he had been using it to look at porn or something and will that mess up my computer. Thank you
