it could have been spyware that keeps on trying to make your icons function inproperly or impact your desktop do a full system scan with Avast and this should fix it..this happenes because avast detects this happening and it stop the impact but it still has to rescan anything that was on your desktop to make sure you are protected
I think you have Spyware.Try reinstall Windows XP.
