    How to turn on Windows Defender

    Hi Guys
    I'm using Win 8 Pro and following some advice on another thread I went to check my Windows Defender via 'all apps'

    When I click on it I just get the following message...........

    "Windows Defender has been turned off and it isn't monitoring your computer"

    I've tried a few things but seem to come up with the same message whichever way I try to start Defender. obviously I'm a bit worried that my machine might be unprotected.

    Any advice?

    I had tried that.

    Just came across a similar solution via Control Panel / Access Centre.

    Cheers as ever...

    I have the same problem when trying to turn on Defender. I checked Services and it's set to manual and not started, when I clicked start, I have following error:

    The Windows Defender service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs.

    I have Zone Alarm firewall + antivirus installed, but turning that off did not help the situation. I also tried setting Windows Defender service to automatic, but upon rebooting it's reverted back to manual and not started.

    Mine is Kaspersky Internet suite 2013. I assume it turned Defender off, but even when KIS is closed down, Defender will not run. It worked fine with KIS and Win 7, so it must be a Win 8 thing.

    That's correct. When you install a 3rd party program like Zone Alarm, some will disable Windows Defender to prevent conflicts since it will be used instead of Windows Defender.
