@Boerdi The error is the games “anti-cheat” feature falsely flagging a Norton process as nefarious and is a false positive detection. Add the PaxDei game directory into Norton exclusions and restart the computer, recheck.
The issue as stated previously isn’t Norton detecting your game as something nefarious, the game anti-cheat software is alerting that Norton is the offensive software. The alert you are seeing is a Windows system alert not Norton. Your best solution would be consulting with the game creators for a solution.
