However, the desktop screen is still "hijacked" and shows a black window telling me my computer is infected, blah, blah, blah.... and the only button you can click on wants to go to psguard.com
I can't change it because it has removed some of the tabs in "Display Properties". I have a "settings" tab and a "screensaver" tab, "themes", "desktop" and "appearance" are no longer there.
there are two entries in the registry that I tried to edit manually, but as soon as I do, something changes them back.
in the section : HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System there are several entries, default I believe should be "0" and they are showing as a "1" but it won't keep the changes.
I'm running the latest AVG free version and also running Microsoft AntiSpyare, scans with both come up clean. I just want to get my display properties window to show all the tabs again.
