When I try and access "MY Computer", try and open up "my documents", or even try and open "My Network Places. The computer system will not allow me to open these items and the screen will refresh and "kick me" off the internet (if connected). Also I am not able to open up the "control panel". It acts as though there is a trojan or worm but when I do a virus scan and use "The Cleaner) the system is unable to find any trojan horses or viruses. ANy ideas?
