I'm assuming this issue to be caused by a virus or spyware though none of my protection/scanning software can find anything.
Layered on top of all of my desktop icons is another icon. Not another shortcut or application. Specifically, an Adope icon. You can see all of the original icons through the other one. All shortcuts work properly. When I look at their properties, the original icon file is shown. When I add new shortcuts, those too are covered by an Adobe icon.
Any ideas what might cause this?
