Help! My computer keeps freezing up! I don’t know what my grandpa did when he was on the computer last, but now everything is freezing up and I can’t open anything. I think he must have clicked something that downloaded a nasty virus. The problem is I can’t get into my antivirus to run a scan and make sure everything is okay, or at least take care of the problem. So I’m at a lost for something to do. I know one thing. My grandpa isn’t allowed on the computer again for a very long time.
