Turn On or Off Real-time Protection for Microsoft Defender Antivirus  

Hi

Are the options five and six still valid for Windows 10 v1709?

Thanks

Bye

Hello balubeto, :)

It sure is.

Thanks ! Everything was fine with the commercial mapping software I have been using for years, and Defender stopped the image exports using Imagemagic. Now I do have anti virus/trojan software, so I just needed to fix Defender which suddenly decided to block me from making maps and exporting as png/bmp/jpg.

And Thanks Brink !

edit;

ImageMagick.

Even thoguh I have Defender off for over a year, it downloaded new definiitons and did a scan. Even though I have scan and it turned off. I fixed a typo or two as well above.

I'm attempting to create a CMD script to toggle Real-time protection on and off. If protection is off, the script will toggle it on; however, if protection is on, the script fails with "Error: Access is denied." Any ideas how to fix this issue?

Code:

@echo off
cls
:: toggles window defender realtime monitoring
:: if DisableRealtimeMonitoring is 1 then it is OFF
:: if DisableRealtimeMonitoring is 0 then it is ON

:: look for DisableRealtimeMonitoring value (0) - if it is found then Real-time protection is ON
REG QUERY "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Real-Time Protection" /v DisableRealtimeMonitoring | Find "0x0"
IF %ERRORLEVEL% == 1 goto found
IF %ERRORLEVEL% == 0 goto notfound
goto end

:notfound
cls
echo.
echo.
echo.
echo Real-time protection is ON - so turn it OFF
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Real-Time Protection" /v DisableRealtimeMonitoring /t REG_DWORD /d 1 /f
echo Real-time protection is now OFF
goto end

:found
cls
echo.
echo.
echo.
echo Real-time protection is OFF - so turn it ON
REG ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender\Real-Time Protection" /v DisableRealtimeMonitoring /t REG_DWORD /d 0 /f
echo Real-time protection is now ON

:end
echo.
echo.
echo.
pause

Run it as an Admin or give it Administrative privileges .

Hello cb360t, :)

If you like, you might see if using the PowerShell commands in Option Four to toggle on/off Windows Defender Real-Time Protection may work better for you.

You can use Get-MpPreference like below to check the current setting.

Get-MpPreference

When turned on, Windows Defender protects its registry key, and would be why you get an "Access Denied" message.

It's a security measure to help prevent malware from being able to turn off Real-Time protection.

I used the reg file to turn off Defender. Then it started telling me I had turned off Defender and I was helpless. Well, I have pcmatic. So I'm neither helpess nor defenseless. Composer update crashed my cmoputer last fall. MS has some serious problems they need to fix. Yes Brink, I know, they will claim they don't make mistakes. And yet they do... :-|

Apparently MS is trying their level best to make more people go to Linux... unfortunately I can't play Everquest on Linux, the nice people at daybreak Games don't like Linux. Yes peanut gallery, Everquest is still around.
