I have a weird disk showing up, I'm not sure what it is. Could be a virus.

I have the two usual drives, Windows (C:) and recovery. But then there is this drive \\?\Volume{4e47eaa3-0000-0000-0000-b0c4e8000000}\

I'm really not sure what it is. I have only just seen it after going into "defragment and optimizing drives". Can someone please explain what this is and if its bad. Its not running at the moment, It says that it last ran 11/08/2015 20:14 at the exact time the recovery ran.
