NFCGate flagged as malware even after multiple followups saying it isn't (github.com)

This reminds me of may of one of my favourite piece of software, Mail PassView, which is (AFAIK) considered Malware bei Windows/Defender because it shows you the passwords you entered yourself in Outlook (but forgot to write down somehwere).

Flagging Malware is hard, and research/dev tools are always behaving at least similar to Malware (because we want to get data/do stuff regular users won't do).

Malware scanners are such trash.

I have the same problem because my installer uses NSIS. And once my DLL also was flagged as a virus / malware even though it's completely legit :/ , everything is signed properly. Anyone knows how to improve this situation ?
