This showed up on my desktop yesterday.



It actually started as a small block in the upper left corner of my screen but I clicked on it and it drags around and changes color when I click on it. I can't delete it or put it into the recyle bin. Double clicking it does nothing. It appears to only be on the desktop because it doesn't show up when I open anything up. I've run AVAST and it doesn't pick anything up. Anybody have a clue?
