I recently had a "Security Alert" when I was on the internet. I immediatley turned the computer off. Now when I start windows I get the "chess Piece" symbol and my logon name but when I click on the symbol windows does not start up. I get the message "Loading Profile setting" but then I get an immediate message that windows is shutting down and my profile settings are being saved. I have tried using the "Restore" utility but I still have the same problem.
