It seems suddenly my computer is locked-down. When I press Ctrl-Alt-Del, it says the administrator disabled Task Manager. When I attempt to load the registry editor, it states that the editor has been restricted by the administrator. I only have one user account, and it is flagged as the administrator. The Microsoft knowledge base gives a fix for this, but I cannot fix it without access to regedit.

Also, when I double-click on desktop icons, it loads the shortcuts properties page. I have to right-click and select open to load programs associated with icons.

These problems appear to be new as of today, so perhaps I have some type of virus. Norton doesn't come up with anything on its virus scan.
