    How to Turn On or Off Tamper Protection for Windows Defender Antivirus in Windows 10


    Starting with Windows 10 build 18305, Microsoft introduced Tamper Protection.

    Tamper Protection is a new setting from Windows Defender Antivirus, available in the Windows Security app, which when on, provides additional protections against changes to key security features, including limiting changes which are not made directly through the Windows Security app.

    Starting with Windows 10 build 18323, you may see a new recommendation in the Windows Security app suggesting you turn this setting on if currently turned off.

    This tutorial will show you how to turn on or off Tamper Protection for key Windows Defender Antivirus security features in Windows 10.

    You must be signed in as an administrator to turn on or off Tamper Protection.



    Here's How:

    1. Open Windows Security, and click/tap on the Virus & threat protection icon. (see screenshot below)

    Has this facility now been turned off as I can't find it, running 18362. The other issues is that no matter how I try I can't run WD Offline Scan.

    Got a little jumpy today having got a Virus warning after downloading netbeans IDE from the official apache site, Scanned it, did a hash check , both reported as ok and then getting a WD warning which had picked up, an thankfully quarantined, a trojan by the name of unwaders.A!ml virus.

    So I decide to try a WD offline scan but ran into the issue of it not working. Anyone with any ideas as to why this would not be working?

    Also I have no idea what "Monegafeb.exe" detailed in the first line of "Affected items" is. Can't find anything in an online search either.

    The path "C:\Users\Tech1\AppData\Local\2d18139fc92404b986600c472cb5043a" is still in the hidden files but the Monegafeb.exe is not as it was, I assume quarantined by WD.

    Should the folder "2d18139fc92404b986600c472cb5043a" be there or do I get rid of it? There are 2 text documents in it, pacepotaro and sof.

    Hellp @techquest,

    Do you have the settings available in Settings like in the tutorial?

    If not, do you have a 3rd party AV installed?

    Hi Brink thanks for your input.

    Yes I see all that you have in the tut and have all on down to the Tamper on slide. But no matter what I try, the offline scan does not run. I have no third party protection on the system.

    If you haven't already, you might see if you may be able to use one of the other options to perform a Windows Defender offline scan.

    Thanks, yes I have tried all 3 options.

    Opt ONE (PS). C:\Windows\system32> Start-MpWDOScan
    C:\Windows\system32> just sits at this promt.

    Opt TWO (CMD). PS C:\Windows\system32> PowerShell Start-MpWDOScan
    PS C:\Windows\system32> just sits at this prompt


    Opt THREE. Get to point 5. and Yes to UAC but doesn't get 6. or beyond.

    Interesting. Are you able to run the offline scan if Tamper Protection is turned off? If so, could be a bug.

    Just tried your suggestion with Tamper Protection off but still the same trying all 3 options of # your2. As you say, interesting. Should I report this through the hub as a potential bug, do you think?

    Okay Brink, thanks for your input and help, they are much appreciated.

    Meanwhile I will flag it to the insider hub and see what they come back with, if they do at all that is, and post back here if there is any result.
