0kb Desktop File Wont Delete and Can't be Moved
So a couple months ago I downloaded a .rfa file (Autodesk Revit) using Firefox. I had to abort the download midway, which subsequently left a 0kb file on my desktop. When I try to delete the file, explorer says it's "Preparing to Recycle" and "discovering items", but no matter how long I leave it, it can never find the file. When I try to rename the file, explorer becomes unresponsive and forces a restart of explorer. It wont let me move the file by dragging it to another folder either.
Malwarebytes' FileAssassin also becomes unresponsive when trying to delete the file. When I try to take ownership of it as suggested in other threads, nothing but an empty command prompt opens.
Can anyone please enlighten me as to how to delete this file on my desktop? It's incredibly annoying!
I would really appreciate the help!
P.S. I'm using Windows 7 Professional 64-bit and I have full administrative rights.
