Here's the lates WTF:

In my tray is showing an alert from the security center saying that the
automatic updates are turned off, but in the admin tools the service is on.
When I try to see the properties it gives "access denied."

Another problem, maybe related(?): I installed MS AntiSpyware, but it only
gives error 101 when I start it. Now I can't uninstall it.

I'm going to try to scan for viruses and such, but any other ideas in the
meantime?
