Does this mean you can't play the game? If that's so, follow this guide: https://smallbusiness.chron.com/make-norton-permanently-ignore-file-68725.html. This makes it so Norton ignores specific files from scanning. If this guide doesn't work, try to google other guides to make Norton ignore specific files and folders.
I don't think Norton is going take a lone indie hentai game developer too seriously (just a hunch lol). Follow the guide and let me know if you can run the game.
