Help! I can't delete a file off of my desktop!

I had a similar problem. There was a file on my desktop which had 0 in size and could not be deleted nor moved. Not even with command promnt. I even did 2 full virus scans but nothing.

What fixed it was actually quite simple:
I downloaded that file again. It didn't ask me to overwrite or change the fail name, even though there was already one with the same name on the desktop. So I had 2 files with the same name, one with size and the bugged one.[ there was no (1) behind the filename either]
So I moved the new downloaded file into my documents and then back to desktop. When I moved it back to desktop, the 2 files merged whitout any dialog box. After that I was able to delete it.
