My PC takes long time to log into the window after the log in screen. Then the window show can't find any network adapter, window firewall is turn off, AVG anti virus email scanner is turn off.....etc. It also pop up a message says that window help service could not start. Even some audio or video player can't function. Window's widget not running.... It seems tht "somebody" have turn off all my setting but I was unable to turn it ON back, everything seems like 'LOCKED'. Any GURU out there. Please help me out here. Thanks.
