Hi,
Of course it does not work, because it relys on WFP. WFP can be easily disabled and do reg add command to add your own rules. I've tested Malwarebytes firewall control. Failed miserably by adding fw rules, even tampering was enabled. Thats why i prefer third party firewalls, that does not rely windows own filtering driver. Sophisticated, "untected" malware can do those fw rules way before windows firewall is even started.
