    Windows 10 Defender - Virus and Threat Protection Not Working


    Hello, I recently deleted some antivirus programs from my windows. Then I came to know that my windows 10 defender was not working properly. I have green tick on my VIRUS AND THREAT PROTECTION option which means it is working properly, but, I can't scan anything. When I click on scannow or update button it doesn't do anything. Under my VIRUS AND THREAT PROTECTION SETTINGS, everything is grayed out and set to off. The solutions I have tried as as follows:

    . I have executed DISM commands and SFC commands in cmd.

    . I have changed some settings in registry.

    . I have up to date Windows.

    In services, three windows defender services are set to manual which neither can I set to auto nor I can start.

    BTW I have checked all google and other threads and can't seem to find any fix.

    Help will be greatly appreciated.

    :)

    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....

    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):
