No correct, it’s not supported, but I thought perhaps it would be easy to figure out. As mentioned before, just about all other advanced security tools work correctly on Win 10 1909.
I have no problems with HitmanPro.Alert, AppCheck Anti-Ransomware, OSArmor, SpyShelter Firewall, TinyWall, Malwarebytes Anti-Exploit and Sandboxie. They all register a system service and driver without any problems. Obviously, Windows Defender also works correctly.
So what’s so special about SpyShelter 15?
