you need to say that "spyshelter firewall" is not "spyshelter" (an anti-keyloger) and spyshelter premium has also this feature. https://www.spyshelter.com/spyshelter-firewall/ https://www.spyshelter.com/spyshelter-premium/ which need a special license which is not available for regular users, those are only usable with questionable offers or by (illegal) kms.
You can replace that autoKMS to "mymalware", if that makes you happy? Here's the an example, how sopthisticated malware targets to windows firewall etc. Sure it does not work, if you're using third party fw.
Good point, @Brummelchen -- HERE is a comparative chart of the several types of security protection provided by the various SpyShelter versions.
simplewall. As easy and effective as it gets. There's a portable version available and both versions get justifiably stellar reviews on Softpedia.
concerning Windows Firewall. If there is no other product well registered for Windows and you tun WF off, it has side effects. Windows Firewall is for somehow unknown reason responsible that other fonts that windows are usable.
Some third-party firewalls take over from Windows Firewall and those integrated with AV or Endpoint Security suites do.
