    Have you tried to restore the service, for example from .reg file from How to Restore Default Services in Windows 10
    (WinDefend, Microsoft_Defender_Antivirus_Service.reg)

    Hi,

    Thank you for posting the query on Microsoft Community.

    Windows Defender Antivirus Service missing, is a problem seen before. Not sure

    what causes this, but most likely it is the presence of certain Other antivirus programs,

    or perhaps some form of malware.

    Run this Microsoft fixit to fix security related issues that could be in Windows Defender Security . This Microsoft fixit automatically detects the issue and fixes it automatically.

    Here is the link to download the fixit: http://support.microsoft.com/kb/918355

    Step 1: Download the Windows defender default registry file.

    Step 2: Double-click on downloaded windefend.reg file.
    Step 3: User account control will ask you for confirmation to run the registry file, so click on YES .

    Step 4: Now the system is asking you to merge the registry content into the existing system registry, so click on Yes.

    Step 4: The Windows defender registry has been successfully updated to the system registry.

    Step 5: Reboot your computer. After rebooting, your Windows defender service will be available.

    Also i suggest you to go through the below link where we discussed the same issue.
