Hi, I was on the computer recently and noticed a tiny tiny blue dot in the top left hand corner. When I say tiny I mean really really tiny. I tried clicking on it to no avail but found I could drag it around the desktop. As I dragged it away from corner I saw the actual shape of the icon, not a dot anymore. Let click does nothing. Right click, nothing. Can't drag it to the trashbin. Don't know what it is or where it came from. Spybot & Adaware do nothing. The bottom "window" changes color and when I shut the computer off it goes off first, but comes back when the computer is turned back on. I will attach a picture of what it looks like. Any help you can provide would be greatly appreciated.
