Ok I downloaded some torrents and I didn't know at the the time but also some free ware. Well after my computer started down loading Trojans n viruses I started deleting all of my games and all files to the games. I was using advanced system care to take off spyware and etc.... But now my computer is saying that I don't have permission to go on certain places on my computer so I started deleting more files that had to with the downloaded games and now all of a sudden I can't get into my windows and my screen is just black and I've been pressing f8 to start up with safe mode and etc.... And still nothing is happening. So pretty much all I wanna know is how to put my computer how it was when I first bought it, like I don't care if I have to delete everything that I put on my computer I just want it to work again so if you could help me out I would be so appreciative.
