    "Unknown" status under "Virus & Threat protection"


    Hi,


    I am using Win 10 Home ver 1903 build 18362.959.

    I have a problem with Windows Security App:

    When I open the Windows Security window, under the "Virus & Threat protection", it reads "Unknown".

    When I try to turn on the Real-time protection using "Virus & Threat protection settings", it automatically and immediately turns off without any messages.

    On the Protection updates window, "Security Intelligence version", "version created on" and "latest update" entries all read "Not available". Checking for updates makes no changes.

    Basic Checks:
    - I have no other antivirus software installed before or now.
    - Computer restarted several times. No change,
    - Windows update is executed: Reports "You're up to date", no flags,
    - "System File Checker" is executed and no flags,
    - DISM CheckHealth is executed and no flags,
    - Computer scanned with latest Microsoft Malicious Software Removal Tool: no flags,
    - I do not have "DisableAntiSpyware" or "DisableRealtimeMonitoring" entries in the registery ie under "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\" etc.

    Additional Checks:
    - "Security Center" Service is running, however I cannot Stop/Restart this service all options grayed out.
    - Executing "Get-Service windefend.Status" in PowerShell as admin gives "Running",
    - Executing " Get-MpComputerStatus" in PowerShell as admin gives "A general error occurred that is not covered by a more specific error code.",
    - Executing "MpCmdRun.exe -GetFiles, gives MpSigSub.log showing that signatures are upto-date.

    Any help towards identifying the root-cause welcomed.

    PS:
    - Please do not reply saying "reinstall windows": My question is to identify the root-cause. I know how to do "clean install of Windows".

    - I am aware of: https://answers.microsoft.com/en-us/protect/forum/all/windows-defender-gui-malfunctioning/9c10fce2-89c0-4db4-97a2-023942e3724e
    Unfortunately, that does not help, as it is related to specific Asus tool which is not used on this computer.

    Thanks,
    -Jim

    :)

    Persistent Threat Message in Virus & Threat Protection in Windows 10

    Hi,

    I have recently uninstalled CCleaner from my PC.

    Under Current Threats in Virus & Threat Protection, I keep getting the message that there's a threat from App"Unknown" status under "Virus & Threat protection" :piriform_CCleaner.

    I've tried the option to Remove this but even after a re-boot the message remains.

    Can someone please suggest how to resolve this?

    Thanks!

    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
