I think there is more to it than that. I'm the only one who sticks USB drives into this PC. Not ready to mark as solved, just yet.

Hi johnblood,

Those mysterious files and folders are a result of the CyberReason RansomFree program that you have installed. See here and here. Nasdaq did a fine job cleaning you up. I don't think you have anything to worry about. Just follow the instructions in the link he provided for best security practices and you'll be fine.

Windows 7 Professional 64-bit SP1

I had this exact same issue on my work laptop, and the help desk had no clue - until I found an article on the company web page saying they deployed Cybereason software a few months ago. Apparently they didn't think it was important to educate the Help Desk on handling these calls. Bottom line: These are benign "canary files" created by Cybereason anti-ransomware software.
