1st impression:
(+) Clean and well structures, easy to: understand/handle/configure.
(+) … e.g. allow, block, or always allow/block processes.
(+) basic functionality actions are done by just single clicks!
(+) had no crashes and found no other misbehave since now.
(-) a little bit hungry for resources.

All advanced features are to be tested and watched by me in the next month(s)…

For now I would say:
Thank you! – Seems to offer all what I need and being made for everyday usage!

Its easy to use and remembers me of famous (an beloved!) “Sygate Personal Firewall” (sigh…: I missed it VERY much, for I found no equivalent replacement in the recent years for that great tool… But now I am hopeful to have found!)

Thank you for the hint; but yes, of course I tried this too, but found it not that convenient and flexible…

With XVirus P.F.Pro I found a (for me useful and important) point:
(-) missing a toggle to block all traffic!
Again I get to the conclusion: I´m really missing Sygate PF …

Thank you for your answer. I hear you. I think I am going to try Xvirus Personal Firewall PRO.
Have a wonderful day.

Had been puzzeld too by this message:
As far as I remember this was due to not having activated the option of watching (scanning?) for behavior (or similar)…

But I tested again and returned to WFC:
Downloaded the current version (had not even noticed before, that WFC now belongs to “Malwarebytes”…!)…
And I now noticed some improvements, which I seemingly missed because I dropped it more than 2 (or even more) years ago.
