The anti-virus vendor is Microsoft; I imagine I will get short shrift from them regarding this issue.

Turns out my py2exe script was just pyinstaller under the hood. Apologies to py2exe.

I guess someone changed the build script script to use a different python packager.

I upgraded pyinstaller using the very latest pip and now the version of pyinstaller at least is 3.3.1. I don't actually know how 
to check the validity of the installed code or the binary stubs.

After rebuilding with 3.3.1 the new exe is 10 bytes shorter and is not recognized as malware by windows 10.
