I discovered this symbol on my desktop. I can not remove it. It appeared about two weeks ago in the top left corner of my desk top. I can drag it to any part of the screen and it will stay there. however, when i shut down or restart it appears in the upper left corner again. I click on it it does not open or do anything. I have tried to deleate it, move to recycle ben nothing seems to effect it. I ran Trend Miicro virus
scan several times found no problems.
Description of the symbol:
It is a small rectangular box, top part completly shaded and bottom half not shaded in. At times the small box appears completly shaded in.
Any help or ideas would be appreciated.
