Disable Defender Antivirus real-time protection module

Overview

About this script

This script improves your privacy on Windows.

These changes use Windows system commands to update your settings.

This script disables the Defender Antivirus Real-time Protection (RTP) module by removing its core library, MpRtp.dll.

The MpRtp.dll library is also known as AntiMalware Realtime Monitor 1. It is a crucial component of Defender Antivirus 2 3 4 5. It works with the Microsoft Defender Antivirus Mini-Filter Driver (WdFilter.sys) to intercept and scan file operations 5 6. It functions as the Real-time Protection module 5 7. It constantly monitors your system for threats 8.

It includes features like:

  • Device Control policies to restrict the use of removable devices and printers 5.
  • Data Loss Prevention (DLP) capabilities to prevent sensitive data from being leaked 5.
  • Monitors your system 9, including scanning files and processes 5
  • Management of exclusions for files and processes that should not be scanned 5.
  • Real-time threat detection and actions based on configuration settings (e.g., block, allow, audit) 5.
  • Cloud-based protection and file submission to Microsoft 5
  • Integration with Office applications and browsers for additional protection 5.
  • Communication with other Defender components 5
  • Browser protection and network scanning 5
  • Controlled Folder Access to protect against ransomware
  • Using Event Tracing for Windows (ETW) providers for security logging 3 5

This script improves privacy by removing capabilities like sample submission and cloud communications. It prevents the system from monitoring processes for suspicious activities and logging events related to threat detections. It may also improve system performance, as some users have reported high CPU usage linked to this module 4. However, this may reduce your system's security by disabling real-time protection against malware and other threats.

Caution

Disabling real-time protection may expose your system to significant security risks.

Technical Details

This script deletes the MpRtp.dll library from %PROGRAMFILES%\Windows Defender\MpRtp.dll 1 2. On older versions of Windows, this file is located at %PROGRAMDATA%\Microsoft\Windows Defender\Platform\*\MpRtp.dll 3.

The MpRtp.dll library registers Event Tracing for Windows (ETW) providers for security logging 3 5. It implements the following ETW providers 3:

ETW Provider GUIDETW Provider Name
8E92DEEF-5E17-413B-B927-59B2F06A3CFCMicrosoft-Antimalware-RTP
7AF898D7-7E0E-518D-5F96-B1E79239484CMicrosoft.Windows.Defender
