How To Kill 'Antimalware Service Executable' In Windows 10

If you have been using the Windows operating system for a while, you may know that Windows is not entirely free from bugs and errors. Not just that, but the operating system is also not entirely secure. However, to deal with security issues, Windows provides users with a built-in security tool known as Windows Defender.

Windows Defender runs an antimalware process in the background that continuously checks and protects your system against malware attacks. The Microsoft Antimalware Service Executable runs in the background and consumes many RAM and CPU resources.

Although Antimalware Service Executable is a necessary process that secures the system, it consumes lots of resources which cause our computer to slow down. What’s worst is that users can’t directly ‘End Task’ the Antimalware Service Executable from the task manager.

2. Disable Windows Defender From The Registry Editor

Since the ‘Antimalware Service Executable’ is associated with Windows Defender, we need to disable the Windows Defender from the Registry Editor. Although you can disable Windows Defender from Settings, it still runs some processes in the background. So, here’s how to disable Windows Defender from the Registry Editor.

1. First, open the Run Dialog box and type in regedit.


2. Now head to the following path – HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Navigate to the following path

3. In the next step, right-click on the Windows Defender and choose New > DWORD.

4. Name the new key as DisableAntiSpyware, double-click on it, and set the value to 1.


3. Stop ‘Antimalware Service Executable’ from Group Policy Editor

If the registry method failed to stop the ‘Antimalware Service Executable’. Then, you can consider this method. In this method, users must change the Group Policy Editor to kill the process.

1. Open the RUN dialog box and type in gpedit.msc


2. On the Group Policy Editor, head to the following path – Computer Configuration/Administrative Templates/Windows Components/Windows Defender Antivirus/Real-time Protection. On the right-hand side menu, double-click on Turn off real-time protection.

Navigate to the following path

3. In the next window, select Enabled and click on Apply.

4. Disable Scheduled Tasks

Windows Defender has a few tasks scheduled to ensure proper security and protection. Since it’s scheduled to start at a given time, users don’t get the option to end the ‘Antimalware Service Executable’. So, in this method, users need to disable every scheduled task associated with Windows Defender to kill ‘Antimalware Service Executable’

1. First of all, open the Windows 10 search menu and search for Task Scheduler

Task Scheduler

2. In the next step, head to the following path – Task Scheduler Library > Microsoft > Windows > Windows Defender.

head to the following path

3. You will see four scheduled tasks. Right-click on all of them and select Disable

Select Disable

5. Install Any Other Antivirus tool

Windows Defender runs when your system doesn’t have any third-party security tool. Windows Defender won’t run side by side with any third-party software. So, if the methods mentioned above failed to disable the ‘Antimalware Service Executable’ from the Task Manager, you must install a third-party antivirus.

Third-party security tools like Malwarebytes and Kaspersky Security are more powerful and capable than the default Windows Defender. For a complete list of security tools, check out our article.
