How to Disable Antimalware Service Executable Windows 11: A Step-by-Step Guide

Disabling the Antimalware Service Executable on Windows 11 can help improve system performance if it’s using too many resources. Here’s a brief rundown: you’ll need to access the Windows Security settings to turn off Real-time protection and make changes in the Group Policy Editor to prevent the service from running.

How to Disable Antimalware Service Executable on Windows 11

Now, we’ll dive into the step-by-step guide. Following these steps will effectively disable the Antimalware Service Executable, freeing up system resources.

Step 1: Open Windows Security

First, open the Windows Security app.

To do this, click on the Start menu, type “Windows Security,” and press Enter. This opens the main interface where you can control various security settings.

Step 2: Navigate to Virus & Threat Protection

Next, click on the “Virus & threat protection” tab.

This tab is where you can see your system’s current protection status and manage various protection settings, including Real-time protection.

Step 3: Turn Off Real-Time Protection

In the Virus & threat protection settings, turn off Real-time protection.

Click on “Manage settings” under Virus & threat protection settings and toggle off the Real-time protection switch. This action temporarily disables the Antimalware Service Executable, but it might turn back on automatically after some time.

Step 4: Open Group Policy Editor

Now, open the Group Policy Editor by typing “gpedit.msc” in the Run dialog (Win + R).

This tool allows you to make advanced configuration changes to your Windows system. Be cautious, as changes here can affect system behavior.

Step 5: Navigate to Windows Defender Settings

In the Group Policy Editor, navigate to Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender Antivirus.

This path takes you to the specific settings for Microsoft Defender, where you can disable the service permanently.

Step 6: Disable Microsoft Defender Antivirus

Find and double-click “Turn off Microsoft Defender Antivirus,” and set it to “Enabled.”

Setting this policy to “Enabled” disables Microsoft Defender Antivirus, which includes the Antimalware Service Executable.

Step 7: Restart Your Computer

Finally, restart your computer to apply the changes.

A simple restart ensures all the settings take effect, and the Antimalware Service Executable should no longer run.

Once you’ve disabled the Antimalware Service Executable, your computer should run more smoothly, using fewer resources for background tasks. However, this also means your system will be less protected, so consider using alternative antivirus software.
