Re: MalwareBytes Premium Reporting Possible False Positive With a File in the Acapela Colibri Voice Bundle
All these engines use definitions along with heuristics that can and do change with time. It's very likely that what VirusTotal had from Malwarebytes was a set that was slightly (even ever so slightly) older and different from what the software itself, as installed on your computer, had.
Something worth reading in this arena is something written by security expert Quietman7, who remains very active on BleepingComputer: Reflections on Antivirus/Antimalware Testing & Comparisons

I do not understand why some seek to separate a person from their actions. The self is composed of an individual’s thoughts, actions, and expression, which are contained in and actuated by the body. What you do and say is the clearest indicator of who you are.
