My computer has to have some kind of virus, but I haven't found out what it is. Basically a few days ago it started going on stand-by on its own, then it shut down once or twice too. Now, every time I turn on my computer in about the same second that it takes to say windows is starting up, it says it's preparing to shut down. Now I don't even have the opportunity to scan my computer again for any virus. Anybody know what bug this is? :-/
