Interesting, I also did a scan with RogueKiller (just because of general security paranoia, I haven’t noticed any symptoms or anything), and it also wanted to upload that file to VirusTotal. It shows up as clean one (link at the bottom of post), and RogueKiller doesn’t find anything malicious to list, neither do Avast, Malwarebytes or HitmanPro. I’d also like to know what it is, but I would think that something would pick it up if it was related to anything malicious.

E: Actually if someone more knowledgeable about these things wants to take a look of it, I can always just send it to you through a private message.
