    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?

    bring up charms menu on right hand side of screen, click settings, click control panel, click window defender, click settings tab, click turn on real time protection.

    I had tried that.

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

    Cheers as ever...

    Hello Skewett,

    If you like, I whipped these up to help make using Windows Defender easier in Windows 8.

    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.
