COMODO Firewall can’t take over the control of Windows Firewall like many other security software such as Kaspersky, Norton.
In the past, that wasn’t a problem, users can shut down Windows Firewall manually.
But in the new Windows 10 ver 1703, Windows Defender has upgraded to Windows Defender Security Center, if users shut down Windows Firewall manually, there will be a warning in WDSC even Windows Security Center has detected a third-part firewall.(see the attachments)
I don’t know whether it is a bug of WDSC or will MS fix it, so I hope COMODO can take over the control of Windows Firewall, just like Kaspersky and Norton and many other security software.
Hello, I am not meaning the Windows Defender, CIS can disable Windows Defender surely.
I mean, COMODO Firewall won’t disable Windows Firewall automatically, in previous version of Windows 10 or Windows 8/7, users can disable Windows Firewall manually, but in Ver 1703, there will be a warning in Windows Defender Security Center if users shut down Windows Firewall manually.
As you can see in the following attachments, pic 1# and 2# both are in the control panel of Windows Firewall, pic 1# is Kaspersky, pic 2# is COMODO Firewall. Then you see pic 3#, Windows Firewall is still working, if I shut it down, Windows Defender Security Center will display a red “X”, just like what I showed in this topic.
With the Creator Win10, the Firewall has to be turned off for the Home or Trusted Network manually in the Security Centre. It does leave the red cross on the Security Centre icon as a warning and it doesn’t seem that is fixed as yet
I just disabled the security center in autostart options (taskmanager → autostart) and the icon is gone. I know that I´m proteced and do not need the icon If a service i.e. Antivirus or CFW is stopped there will be a system notification.
So the real issue is that CFW does not turn off Windows firewall automatically, you have to do so manually.
If you turn off Windows firewall manually, then you will always get the red X, no matter what 3rd party firewall you run.
Even if you install Kaspersky Internet Security, but before that, you manually disabled Windows firewall, you will get the red X.
To add something to discussion. It looks like problem might be with Windows’s “split personality” (classic desktop UI vs Modern UI).
I have Comodo Firewall installed and Windows Firewall disabled. You can see in my screenshot of Security Center (Modern UI) it shows Windows firewall is off, that is also why it shown as off in tray.
But if you check Security and Maintenance screenshot (classic desktop UI) you can see it detects Comodo firewall and its status as turned on. Even better if you click View installed firewall apps it shows status of Comodo firewall as on and Windows firewall off.
Recently, I have seen people suggest to leave Windows Firewall running, together with CFW, on Windows 10. I don’t really understand the logic in this, or why anyone would want to have 2 potentially conflicting firewalls running at the same time, but that’s what they are saying.
What’s the right approach?
Do not disable Windows Firewall by stopping the service. Instead, use one of the preceding procedures (or an equivalent Group Policy setting) to turn the firewall off. If you turn off the Windows Firewall with Advanced Security service, you lose other benefits provided by the service, such as the ability to use Internet Protocol security (IPsec) connection security rules, Windows Service Hardening, and network protection from attacks that employ network fingerprinting. For more information about Windows Service Hardening, see http://go.microsoft.com/fwlink/?linkid=104976. Non-Microsoft firewall software that is compatible with Windows Vista and Windows Server 2008 can programmatically disable only the parts of Windows Firewall with Advanced Security that need to be disabled for compatibility. You should not disable the firewall yourself for this purpose. Stopping the service associated with Windows Firewall with Advanced Security is not supported by Microsoft.
Can we have a definitive statement from Comodo concerning whether the Windows Firewall 10 should be left on or off, and if the answer is off, then why is it not turned off during installation in a similar way to every other security suite which includes its own firewall? I really don’t want more endless discussion concerning the pros and cons, simply is this an error during install, or designed on purpose to have the two firewalls running simultaneously. Thank you.
