I had a similar problem, it wasn't the box that you mentioned but it was a video of a grandma kicking a baby, there were no processes/hidden processes to speak of and no installed programs nor registry entries. How I got rid of it was pure luck, normally the mouse moves over it like its part of the background but one time I saw something flash when I moved over it so I tried a couple more times and a frame appeared around it with a small almost invisible X in the corner and click... gone. Don't know if there is a similar situation with your bug.
