Display properties problem!

I have a problem. For some reason I have no desktop options. I go to display properties,desktop.........and for some reason all my options are highlighted in grey and I cant select any of them. Anyone have any idea why that is? I cant put a backround wallpaper or anything.

And I have already downloaded spyware doctor and spybot. Ran both and removed a couple trojans. I now have my previous backround back both there is still no options in the display menu, there is no way to change the wallpaper. Here is a screenshot so you can see what im talking about.

 

I would suggest stating here and let one of the gold shields help you thru this. Since you removed one or two infections there may be others and any one or more of them could cause this problem.
