What do i do? I am the administrator on my computer but i have been denied all administrator rights?

Hi everyone

I am using Windows Vista Home Premium, I believe i have a virus. It has disabled all my administrator rights and has disabled my Norton Internet Security. I have tried uninstalling Norton and installing Avast, McAfee and Kaspersky. But whenever i try and install them the computer keeps telling me i do not have administrator rights. My Ctrl+Alt+Delete has also been disabled. I have tried to use Regedit and other methods but it doesnt work.

Please help me :)

Windows Vista has a hidden default administrator account which actually has full system rights. Regular users in the administrator group no longer have full system rights in Vista. Do a google search on "Vista default administrator" and you will fond instructions telling you how to enable the default administrator account.
