    Windows Defender


    Why can't I turn on Windows Defender?
    I have gone to the action screen and clicked on turn it on, nothing happens, no message at all but it stays off.

    Hello Kaycorp, and welcome to Eight Forums.

    Windows Defender - Turn On or Off in Windows 8

    If you have a 3rd party AV program installed, they will usually disable Windows Defender until you uninstall the AV program.

    Could this be the issue for you?

    I thank you for the quick reply. I don't believe I have another virus protector on my unit. Is there some way I can check?

    I originally had PANDA on my system but removed it as per directions from Microsoft Answer Desk.

    You could check in Programs and Features to see if you may have an AV program installed.

    Programs and Features - Uninstall or Change a Program - Windows 7 Help Forums

    Since you had Panda, you might see if using the Panda uninstaller below may help if Panda didn't uninstall properly for you.
