Welp seems that isn't exactly the case. Bitdefender has a form for false positives here: https://www.bitdefender.com/consumer/support/answer/29358/
Could you report it as a false positive? Hopefully the more people who report it, the earlier it will be looked into by Bitdefender.

I love your mods but given the land scape your mods will be barred until fixed.

That is simply a false positive. This happens all the time with mods, there's nothing I can do about that.

There is no malware in my mods. All the code for my mods is available here on GitHub. If you want to be sure, you can even build the mod yourself.

You can also check what different scanners detect using something like VirusTotal: https://www.virustotal.com/
