I'm having problems on my home PC. I recently got a virus that made a lot of pop ups on my IE eventhough I haven't been using it for months. A brother of mine suggested that I update my VP but the computer wouldn't allow me to and now my PC is shutting down on its own after 20 min after it's been cut on. I tried downloading new VP but my computer wouldn't let me and I tried system restore, but when I click next to confirm the restore, it does nothing.

Please help me!
