My 16 yr old was on my laptop the other day and got a pop up telling her there was a virus and to click OK to fix it. She says it would not go away so she clicked it and it told her it needed to shut down. No I can't log on Windows. If I click on the user and try to log on it says "logging on, saving your settings, logging off, please enter your password to log on" and just continues to go in this circle without attempting to actually log in. I have tried safemode and can't do it from there either. How can I fix the virus if I can't get on the computer!
