I was a total fucking-retarded-noob some minutes ago (and now). Well, I have downloaded some msn hacking tools (because a friend of mine was irritating me).My avast! detected viruses and autorestricted them. But I was a idiot and executed a one called "MSN Hacker.exe", and when I executed it it disappeared from my desktop (it was there) and it was keeping being executed and the windows task doesn't get rid of it through the "kill process". and the avast! don't detect it as a virus.Then i restarted the pc and it was gone but now a "IsassNonCrypted.exe" keep poping up and avast ask me if i let it run in sandbox mode or not. Right now i'm doing a complete scanning process of my pc with avast! . I want help, please !!! sorry to bother and sorry for my english thanks!!!
