I have just updated Malwarebytes (Free, ver. 220.127.116.11), and recently it just detected my file as Malware.Heuristic.1001. I have scanned this with Windows Defender, and have submitted a sample to VirusTotal, both showing no detections. Although I'm fairly sure that this is a false positive, I can't be really sure until it is confirmed.
The log for the recent scan is shown below. Additionally, the original report log file and the detected file is attached below.
