Disable Defender Antivirus copy accelerator library

Overview

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script removes the Defender Antivirus copy accelerator library (MpDetoursCopyAccelerator).

This library is referred to by Microsoft as Malware Protection Copy Accelerator Detours Dll 1 2 3. It is a component of Defender Antivirus service 4.

This component monitors and intercepts file copy operations, potentially blocking the copying of certain files 5 6. It optimizes scanning by examining copied files for potential threats after a certain number of files have been transferred 7.

The library uses Microsoft's Detours technology 3. This technology intercepts and monitors system functions 8. It allows Defender Antivirus to examine files during copying 3.

Removing this library may improve privacy by reducing file operation monitoring. It may also enhance system performance during file copy operations.

However, this action may reduce system security. Without this component, Defender may not scan files during copying, allowing malicious or unauthorized files to be copied undetected.

Caution

Disabling this feature may expose the system to security risks because it may prevent Defender from monitoring and scanning files during copying.

Technical Details

This script removes the library from the following locations:

  • %PROGRAMFILES%\Windows Defender\MpDetoursCopyAccelerator.dll 4 6
  • %PROGRAMFILES(X86)%\Windows Defender\MpDetoursCopyAccelerator.dll 9

On older Windows versions, the file may be located at:

  • %PROGRAMDATA%\Microsoft\Windows Defender\Platform\*\MpDetoursCopyAccelerator.dll 1 2
  • %PROGRAMDATA%\Microsoft\Windows Defender\Platform\*\X86\MpDetoursCopyAccelerator.dll 2

This script uses Batch (batchfile) scripting language.

Not Advised

This script should only be used by advanced users. This script is not recommended for daily use as it breaks important functionality. Do not run it without having backups and system snapshots.

Implementation Details
  • Language: batch

  • Required Privileges: Administrator rights

  • Compatibility: Windows only
