Mysterious Random Folders

Ask the Doctor LogoI have four hard drives I use for storage. One of my drives is a 1TB WD Caviar Green. A folder named “35c7b77f9e7bab635e2efb4b74b9” keeps appearing, with a file “MPMiniSigStub.exe” and a bunch of files with names like “1.81.790.0_to_1.81.799.0_mpasdlta.vdm._p.” When I delete the folder a new one with a similar randomly generated name appears in its place, with similar files in it. I scanned with Malwarebytes’ Anti-Malware, Norton 360 4.0, and Microsoft Security Essentials; none of them detected anything bad. I have also “hidden” the folder, but it reverts back to non-hidden status.
