Thank you for the report. We have been dealing with that one for a while, it flags the runtime dll and not the game.exe itself. We have sent reports to windows but they are not changing their mind, we will have to keep updating the NWJS version it runs on, to stay ahead of the curve it seems, thanks again.
(When we uploaded the game to steam, that file was not a problem, where previous versions of NWJS did cause that problem.)
