This is new kind of virus, I guess.I was infected by it too. All my folder in external hard-drive had become shortcut. I didn't know how to get my folder back that had turned to shortcut to become a folder again without loosing any files. I was searching through web, and suddenly found a strange solution, which worked nice.

change your directory to the affected drive or folder. i.e H:/ and press Return/Enter.
