I have something I've never seen before. I have an XP Pro SP3 on a networked computer where someone decided to play games and surf the net!. The next day, nothing worked, desktop icons were there but wouldn't open, nothing would open anywhere in the computer. I booted into safe mode and the only option I had was "Windows Vista!" This computer never had Vista on it. I finally got into safemode through msconfig, no icons showed up at all, but I was able to, through task manager, start tasks and maneuver around the computer, and was actually able to run combofix. I wasn't really sure this was a virus, but thought couldn't hurt. Didn't seem combofix found anything, but it did take me to restore, and I was able to restore to an earlier date. Computer is working now, ran every virus scanner I could think of, came up with absolutely nothing. The only curious thing is when I go into safemode using F8, I get the same thing....no safemode options, only Windows Vista. If I go ahead and choose this only option, it takes me to XP as it should. I searched the knowledge base and have not found anyone who has come across this before. Does anyone know what might have happened, and, more importantly, do you think this computer is ok as it seems to be? I can still boot into safemode through msconfig if I needed to, and I get all the appropriate options. I don't know that I need to "fix" anything any more, just really need to know what this person might have or might not have done. Thanks in advance for your input!
