    I found a folder with a randomly generated name (35ad7f9d92...) on my portable hard drive and it asked me for permission to view, which I allowed so I could see what files were in it. In it were $shtdwn$.req, an mrt exe file, and mrtstub. I immediately googled what they could be in case they were malware and most google results said that they were most likely just microsoft malware removal files. I recently took my laptop to the geek squad to get cleaned up, which is possibly where the file coud have come from, but I very rarely plug my external hard drive into the computer. Yesterday was maybe the second time since I took my laptop to the geek squad. The file didn't show up until today.

    The reason I'm posting rather than just deleting the files, like other posts suggested, is because when I reopened the hard drive's file so i could delete the files, a new randomly named folder (4a1a9f3...) that wasn't there before was right above the first, also asking me for permission. Also the original folder no longer contains the mrt files, it only contains the $shtdwn$.req file now. I'm scared to give the new folder permission in case it is an actual virus.
