Microsoft Defender Threat Service has stopped [SOLVED]

    PLEASE HELP ME

    I am showing the shield icon with a red X on it.  When I open Windows Defender Security Center it says that the Threat Service has stopped.  Restart it now.  When I click 'Restart Now' it does nothing.  If I choose the shield icon out of the list on the left side of the screen and click on the virus and protection settings next to the gears it shows real time protection is off.
    When I click it to 'on' User Account Control pops up and I choose Yes, then it goes back to the screen but stays on off.
    I'm not sure what it causing it or how to get rid of it either.

    I followed the steps quoted, however it had no effect on the issue.

    I found that other previously installed software (i.e. Spybot Search & Destroy) was causing the issues. When Spybot S&D was uninstalled, the Microsoft Defender Threat Service has started to work as expected.

  • Glad to hear that your issue has been resolved, you are right that 3rd party applications sometimes cause the system service issue.

  • You sir just made my day! Not sure why/how did this happen? Anyways, thanks a lot!

  • After you click "Restart Now" you were probably wanting something to happen right away.  You have to have patience and wait a few seconds longer then should connect to change red X to a green check and you're good to go.

  • OMG THANK YOU SO SO SO SO MUCH!!!!

    This worked PERFECT. 

    I installed AVG and it was a VIRUS called Heartless and made it seem like it was installing with a 15 second gap in between so if u click again thinking its not loading it made another one. So I figured out how to Get rid of it and the FOLDER I FOUND FOR IT was called HUMOR. Im not going to LIE, It was FUNNY at FIRST until I killed my WINDOWS STUFF. Now I need to see if I can UPDATE. That was messed up to. 

    THANKS AGAIN. Email me j-sinn@hotmail.com if you have a GOOD CLEAN COPY of a DECENT SPYWARE PROGRAM. I REALLY LIKE AVG TUNE UP but I cant seem to find one and the Trail Version says its deleting stuff of your PC but its really NOT. Unless u have it Registered and the KEYS NEVER WORK.

    THANKS AGAIN
