Log in to your spare admin capable account and see if that works OK. Account damage is rarely repairable and Microsoft has never claimed we can fix it. Example at http://windows.microsoft.com/en-US/windows-vista/fix-a-corrupted-user-profile
That's no fix.
i have Pctools and spybot installed in my computer, but somehow i got a virus on my computer. I down loaded and ran Malwarebytes Anti-Malware, it found a trojan window-locked virus and cleaned the system, however I still have a problem when i double click on my ICons, they will not run, they only way to execute the programs is by clicking on the right mouse and selecting"run as" then unchecking the box under "current user" section with the statement 'protect my computer and data from unauthorized program activity", then it will run. How do i fix the Icons to run again ??
