Pyinstaller 4.2 produced exe containing viruses ?

[kevpython]

I'm using pipenv so I created a new clean virtual environment and installed an earlier version of pyinstaller in there (4.1)
Then I created an exe from a hello world script. The produced exe at least wasn't complained about by my local windows defender and it reported no threats detected when scanned , I then checked it on Virustotal website against thier 60 virus scanners and at least 15 of them came up with various trojans threats detected even the microsoft one hosted there (but my up to date local windows defender said it was clean) . I don't know what to make things (so I test some older pyinstaller produced exe's from a few years ago that I made on another system and these also get a few trojan threats detected when uploaded to virustotal (but only 10 or so now). I don't really know what to do about this, it doesn't make for good confidence in any distributable exe's you create if they are going to be flagged as trojans to recipients .
Could someone else check please and tell me what results they get for a pyinstaller 4.1 or 4.2 produced hello world exe on virustotal site.
thank you in advance
