Malware in Ubuntu 13.10?

Question

This is the situation I'm dealing with:

I plugged my USB in my laptop, then I created a folder within it, and nautilus stopped working for a while, I unplugged the USB and plugged back in, BUT this time there was 2 folders created, I have no access to anyone of them from Ubuntu, not even starting nautilus as root, the only way to see the files is in a Virtual Machine using Windows XP.

When accessing the folder via Terminal and typing "dir" within the folder it'll show this:
