My computer had a serious virus attack, I was wondering if there is a way to restore my hard drive to get all my files back, because I had very important files on it. It'll take very long to get them all back and alot of them I cannot even get back. I really need help because I really need to restore my computer. And I didn't have a back up either or anything to store my files in. It seems impossible to me but I really need help.
