From heise, Germany: "Attackers are currently actively exploiting a critical malicious code vulnerability (CVE-2021-1647) in the Microsoft Defender virus protection system. To what extent this will take place is currently not known. The error can be found in the malware protection engine. Microsoft states that version 1.1.17700.4 is fixed. The update will be installed automatically." How can Simplex users install this update in Win7? Thanks!
It can be done, here is example from my still unreleased tool Windows 6.1 Kitchen Code: if exist "%IMAGE%\ProgramData\Microsoft\Windows Defender" ( echo KB915597 - Windows Defender Definition if exist "%IMAGE%\ProgramData\Microsoft\Windows Defender" ( if exist "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates" ( takeown /F "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates" /A >nul 2>nul icacls "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates" /grant Administrators:F >nul 2>nul rd /q /s "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates" >nul 2>nul ) ) md "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates" md "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates\Updates" md "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates\Backup" "%~dp0apps\7z\%PROCESSOR_ARCHITECTURE%\7z.exe" x "%~dp0updates\mpas-fe-%ARCH%.exe" -o"%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates\Updates" >nul if exist "%IMAGE%\Windows\System32\MpSigStub.exe" ( takeown /F "%IMAGE%\Windows\System32\MpSigStub.exe" /A >nul 2>nul icacls "%IMAGE%\Windows\System32\MpSigStub.exe" /grant Administrators:F >nul 2>nul del /q /s "%IMAGE%\Windows\System32\MpSigStub.exe" >nul ) move /y "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates\Updates\MpSigStub.exe" "%IMAGE%\Windows\System32\MpSigStub.exe" >nul icacls "%IMAGE%\Windows\System32\MpSigStub.exe" /setowner "NT SERVICE\TrustedInstaller" >nul icacls "%IMAGE%\Windows\System32\MpSigStub.exe" /grant:r Administrators:RX >nul icacls "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates" /setowner "NT SERVICE\TrustedInstaller" >nul icacls "%IMAGE%\ProgramData\Microsoft\Windows Defender\Definition Updates" /grant:r Administrators:RX >nul attrib +h "%IMAGE%\ProgramData" >nul )
you should have posted or asked that question here instead edit - because it's an MS defender engine update, it is not part of the simplix pack
