My PC recently got a fairly nasty virus (W32-Sinowal-based Maximus! or something along those lines) so we had to get it wiped. A few days later, my computer was all messed up again. I can only boot up in Safe Mode, my sound doesn't work, and it is running slower than normal. I need to find out if I have another virus (although the guy who fixed it downloaded Norton Anti-Virus and it seemed fine for a few days) or if maybe my computer is just dying. It's about three years old and apparently it was outdated before we even bought it. Is there any way the virus could have affected the computer's hard drive or whatever (yeah, I don't quite know what I'm talking about) or have I maybe gotten another virus? No clue what is going on, so any help is appreciated.
