I got a game program off a friend and loaded it onto my laptop. I run Vista and since I loaded it the computer has been running really weird, sometimes not even booting up. I asked my friend where he got the software. He said there was a warning about sharing the software. If it was shared a thing called "Fahrenheit 451 digital signature", would "burn" the computer OS of the computer it was shared to. He said it was their copyright protection. Any one heard of this and how do I get rid of it??? It looks like it going to wipe my OS if I don't stop it!!! Help.
