My son's computer has windows 7 and uses security essentials. I'm pretty sure he has a virus. When he logs in, the mse icon first spins in green, then spins in red and then windows shuts down because of a potential threat. It happens when he attempts to log into both users. What can I do to help? Appreciate your help.
