I tried to use Task Manager only to be greeted by the message "Task Manager has been disabled by your administrator", and the pc then shuts down and reboots, which is strange as I am the administrator. Googled some solutions, one of which was to change a value in the registry. Start > run > regedit produces the same result, only the message is "Regedit has been ............" followed by the shut down and reboot.
Tried to perform a system restore, and as soon as you click on "Restore to an earlier date" the pc shut down and rebooted.
Hopefully someone can give me some guidance on this as I don't know if this is a result of malware/virus or what.
Thanks in advance
