Magically reappering folder (Virus?)

Hello SevenForums Community,

I have this weird problem on Windows 7 Ultimate (which could be malware or a virus). Basically I've been sending an old empty folder to the recycling bin and then clearing the recycling bin to remove it. But after a period of time (I havent put my thumb on exactly what the trend is yet) it magically reappears on my desktop. I have done a MalwareBytes scan using their most current definitions. Including a scan from MS Security Essentials but this yields no infections found. Has anyone come across this behaviour before? Has my Machine been comprimised?

The folder is named Rory Music 2 and it is one which I created myself. I had removed all of its contents before deleting.

The only time I have had files reappearing was when I had a defrag program running in the background (PerfectDisk). Very unsettling until I discovered the reason.

I have found out what was causing the issue:

I had been ripping some music off of a CD to put onto an MP3 device and set WMP to rip to this Rory Music Folder and in doing this Windows also added it as a location to my Music Locations so obviously it must had been recreating the folder because of this reason.
