Thumbs.db:encryptable

Hi,
I was scanning with Superanti Spyware, and I kept on seeing it bring up a file called Thumbs.db:encryptable

What is this file? It is really concerning me? What worries me most about it is the fact that it has a : in it, when normal windows files dont have this. Is this dangerous? Thanks for your help

 

What was the exact message that SuperAntiSpyware said about this particular file?

This explains what thumbs.db is

Superanti spyware didnt see it as a threat, but I was seeing what files its scanning, and Thumbs.db:encryptable was one of those files. This file was amongst my folders that had pictures in them. It scanned it in almost all the folders that I have pictures saved in. The weirdest thing is that I set my computer to show hidden files and folders, and also so it shoes operating files, like thumbs.db, I was finding thumbs.db, but I couldnt find Thumbs.db:encryptable, and I was searching in the folders where Superanti spyware said it scanned them in. Why isnt it showing up? I even tried ti find it with search and I still couldnt.
