It sounds like you may have some kind of spyware or malware and or possible viruses. Can you see if you are able to delete any files in safemode( F8 or Assist Button)? Try scanning the computer for spyware/malware and or viruses if you can. Run System File Checker(Windows 7 or Windows 8). If still does not, try Windows System Restore and restore the unit back to a date that the unit was working.
