I am trying to remove MacAfee Site Advisor for Internet Explorer. But I get an error message saying "You must be an administrator to uninstall MacAfee Site Advisor". In the bacground there is a progress bar that says "Could not find symbol: IsAdmin". I am in Safe Mode under the "Administrator" account. How can I get rid of this so I can completely remove MacAfee because I need to re-install it. If I don't remove in entirely, I cannot re-install it. I have tried to. Any ideas?
