why does my virus protection say that it has atc4.detection malware?
Releases are built on a Mac, so the malware notice surprises me. Some aspects of the game engine (like a custom application icon) sometimes get flagged as false positives with certain virus scanners. What's in the full report of your virusscanner?
Always upload files to virustotal before running. I'd say this game's exe is clean despite some detections.

You mean in Zombie's Retreat? I can't remember, ask Siren.. or check the guide.
