Wrong way. I'm not looking for double protection and that kind of stuff. Standalone EIS doesn't work properly, at least for me. It's the firewall that seems to have issues with the broadcom driver. When I turn EIS' firewall off, things work fine. With Comodo instead of EIS' built-in firewall, it works perfectly well. Outpost has issues with the broadcom driver as well. Not on Win8.x, but on Win 10. Microsoft has changed the underlying network system with Windows 10. That's why about every firewall didn't work anymore unless they were accordingly updated. To me, it looks like only Comodo did their job right. Emsisoft, GData and Agnitum failed to do so. Not to mention that Online Armor never worked with Windows 10.
So please read the content of the topic first before you lead the discussion into the wrong direction. Thanks.
