The false positive reported by some antivirus software has been professionally fixed.
I had to roll back the game engine 1 year and 1 month back, because nothing else helped. Your AV software should now be happy but I'm not sure the game itself will be stable - a considerable amount of work and bug fixes had been discarded in order to please the Windows Defender.
Sorry for the inconvenience.
