Disappearing wallpaper

[Guest]

Whenever I boot, my wallpaper is missing, replaced by a solid blue screen.
Everything else is fine. If I go into the Display Properties -> Desktop, it
shows the correct picture selected, and is called "Internet Explorer
Wallpaper" in the selection box. If I choose "none", the Apply, then choose
the correct one again, and Apply, it returns to the Desktop. Another reboot,
though, and it disappears again.

Is this a spyware removal issue? Virus? I've scanned with Trend Micro and
found nothing. Do I need to edit my Registry?

Your suggestions on troubleshooting please.

Thanks,
Gene

Turn off active desktop and see if that works.
