Scan the PC for viruses and malware.
The original folders have become hidden and the Shortcuts are actually linked to an executable file.
Your PC is infected with a very peculiar virus/malware that does this and usually transfers onto a rig through a Pen/Flash drive.

Recently you have plugged some portable storage device into your PC which had not been scanned for viruses.
