Hello. I have a home computer with windows XP and I have lost my administrator rights. Most likely a virus or a hijacker has taken over but i cannot do anything to clean up the computer. I cannot uninstall, run the virus program or even reinstall XP. Is there anything I can do to gain access back to my computer? Please help.
