Thank you for reporting, everybody. I can only assume that the method I use for packaging the exe is so common in the world of malicious software, that antivirus software is paranoid beyond max. I'm looking into a promising solution.
UPDATE: Should be better now. Still getting 6/8 false positives on the 64/32 bit versions though on Antivirus. Microsoft defender deletes the 64bit version on download, which can be solved by going to Virus & Threat protection and then Protection history, where you then have to allow the file, upon which you should be able to download it.
This is not great. I hope to have time to figure out how to compile this cleaner soon-ish. [update] I figured it out but not sure it helped.
