    Repeated virus threats to Defender in last 3 days


    I am usually quite conscious of possible computer threats but I received an invitation from a friend that said it required Adobe Flash Player. So I clicked on it and it installed but nothing happened. Then I discovered that Flash PLayer was discontinued in 2020. Since then about 3 days ago Defender's Virus Security has stopped quarantined or removed 8 severe threats to MSBuild.exe. What should I do?Here is what is being detected:Trojan:MSIL/Coinminer.UF!MTB

    :)

    My virus & threat protection is not showing

    I am writing to seek assistance with a problem related to Windows Virus and Threat Protection on my PC. Unfortunately, the feature has become invisible, and I am unable to access it.

    Issue Details:

    • Operating System: Windows 11
    • Problem: Windows Security (Virus and Threat Protection) is not visible.
    Steps Taken: I have tried the following troubleshooting steps:

    1. Restarted my PC.
    2. Checked Group Policy settings.
    3. Reset Windows Security app.
    4. Ran SFC and DISM commands.
    However, the issue persists. I kindly request your guidance on resolving this matter. Could you please provide instructions or further steps to restore Windows Virus and Threat Protection?

    Cannot turn on Windows Defender virus protection

    I had the same sort of symptoms. In the Windows Security Center, under Virus and threat protection, it said "Your virus & threat protection is managed by your organization."

    I note you mentioned the Registry Keys under HKLM/SOFTWARE/Microsoft/Windows Defender. Nice spotting, but it seems like there is another key that is causing the problem for some users.

    Steps to a solution:

    1. Press the Windows key and type "regedit"
    2. On the regedit icon that appears, right-click and select Run as Administrator.
    3. Navigate to the folder located at HKLM\SOFTWARE\Policies\Microsoft\Windows Defender (You can paste this into the address box at the top of the window, or navigate manually using the side directory structure)
    4. In this folder, there are probably two keys. Right-click and Delete the DisableAntiSpyware key.
    5. Exit regedit, and return to the Windows Defender settings screen (refresh it if necessary). Windows Defender should have the scan options available and working.

    Solution adapted from here, with a much more detailed solution here.
