I dont really know what happened, but I guess my dad installed some viruses on this computer. I ran all the spyware programs / avg virus and detected / cleaned all the viruses out. The only problem now is that I cannot run regedit because it says that it is disabled by the administrator and the run option that I need is also gone from the start menu and is also disabled from the running when i press the windows key and r. Aso the time box on th taskbar shows ???? marks in the end of the time. I posted a screenshot. Can anyone please help me? thank you.
