Thank you very much for the prompt response.
This very same false positive with Malwarebyte keep happening at each version on Virustotal, and only with Virustotal (Malwarebytes does not flag the file as malicious on my machines, and your feedback confirm that).
I've reported the issue to them various time since then and all what I got is that they are not responsible for the result of the scans and that the vendors must be contacted (even if I repeated countless times to them I already did it being confirmed the file is clean, and that their own policy informed users that Virsutotal uses custom configuration for the scan which may led to results different from commercial product, so they must respond of that differences).
I've contacted them again pointing out your answers about that the file should not be flagged, I hope in a more appropriate support from Virustotal this time.
