    Windows defender -- virus threat protection -- won't restart


    How does one fix this problem? Windows security virus and threat protection says it needs to be restarted. However, when an attempt is made to restart it, it reports, "Unexpected error. Sorry we ran into a problem. Please try again." Trying again and again gets the same error.

    I do not get this error on four other PCs running Win 10 64 pro.

    Thank you in advance.

    virus and threat protection

    Virus and threat protection has stopped and will not restart, Windows 10 ver 1709, antimalware client ver 4.12.16299.15 . SuperAntiSpyware installed.

    I have tried most of the suggestions from the support pages, all have been ineffective. Any suggestions

    windows defender virus and threat protection

    i am not able to turn on the virus and threat protection function of windows defender in my windows 10 laptop....

    while i was trying to download one key generator , an additional a software named KOMETA browser also installed without my knowledge.......

    and it changed the startup menu , start icon , and a small gadget deck in my desktop. and i tried a lot to uninstall the kometa browser , atlast i found the solution in malware tips.com . by looking down the procedures, i downloaded Adwcleaner to remove
    adwares , at that time windows defender virus and threat protection went off.... i also downloaded Malwarebytes to remove the browser ads... and i uninstalled both software . and when tried to scan my laptop with windows defender , it asked me to restart
    virus and threat protection , but when i tried to restart it , showed a dialogue box reading "Unexpected error. Sorry, we ran into a problem. Please try again". and now i am not able to scan with windows defender....

    Windows defender -- virus threat protection -- won't restart

    Window Defender's virus & threat protection service has stopped

    There seems to have been a hiccup in the Patch Tuesday updates that might need to be resolved with some unconventional methods of restarting the Threat Service (Windows Defender Antivirus Service):
