    Cannot Turn on Windows Defender Firewall


    Happy New Year,


    Re: Windows Defender Firewall, Windows 10, Dell Desktop


    This evening I noticed the Windows Defender icon had a red X. I tried to open the Security Dashboard but nothing happened. I then opened Windows Security but it was completely blank. Firewall & Network Protection indicates: "Windows Defender Firewall is using settings that may make your device unsafe." Domain, Private and Public network firewall settings were all off but with green check marks. I clicked Restore Settings only to have it run on and on and on...until I finally closed it down.


    I tried several suggestions found in this community such as: checking Services to ensure the Firewall and Baseline settings were started and on Automatic; restoring to an earlier point and accessing the Firewall through the Control Panel but to no avail. Each time I clicked on the Firewall in the Control Panel, the blue circle would twirl and twirl until the panel grayed out and finally closed.


    Needless to say not having a Firewall concerns me but I am afraid I will cause more damage if I install another security app. One last thought, the automatic scans which runs daily by Windows Defender and Malwarebytes found nothing unusual.


    Thank you in advance for your assistance.

    :)

    Hi Faye,

    Third-party antivirus programs usually have their own uninstallers provided by the software developer. We suggest checking the developer's website or contacting their support team for assistance with uninstalling their program. After fully uninstalling the
    third-party antivirus software, you may turn on Windows Defender by following these steps:

    • Click Start.
    • Type Windows Defender Security Center and press Enter.
    • Click Firewall and network protection.
    • Click Private (discoverable) network and click On.
    • Click Public (non-discoverable) network and click On.

    Let us know if you have any other concerns about Windows Defender.
