Help with removal of random file on desktop!!??

I have a random file on my desktop on my macbook pro
I cannot move the file, or rename, it or delete it or get info on it. I have tried command delete, tried using an application of CleanMyMac but that didnt pick it up.

I cleaned the cache etc on my internet browsers and nothing will move this file.

The file is a black document with a fold in the top right corner and has the label of... productimg1284318617343.jpg.crdownload

Can anyone help me remove this file

Cheers

Download this free utility:

TrashIt! (free)
Downloads – NoName ScriptWare

If you drop either a folder or file(s) onto TrashIt's program icon, 
it will delete what you dropped on it, no matter where those files or folders reside. (In other words, they don't have to be in the Trash can.)
