ESET Antispam.xnk?

I just noticed a file on my desktop that I don't think was put there by me...
ESET Antispam.xnk It's only 276 bytes. It was created and last accessed yesterday. Does anyone know what it is and why it might be on my desktop?

 

Typically a file with the XNK file extension is a Microsoft Exchange shortcut file. ESET does not install such a file. I suggest that you perform an on-demand scan; detailed instructions can be found here:

Also, you can submit the file to us for review using the following knowledgebase article:

Turns out that somehow I dragged and dropped the ESET Antispam folder from Outllook onto the desktop. I deleted the desktop copy without affecting Eset's antispam for Outlook.
