Turning off the Antimalware Service Executable in Windows 11 might be necessary if it’s causing your computer to slow down by using too many resources. This service is part of Windows Defender, which is designed to protect your computer from threats. However, if you need to disable it temporarily, you can do so by modifying some settings. Keep in mind that doing this can leave your computer vulnerable to malware. Make sure you have another antivirus program in place if you decide to turn off this service.
How to Turn Off Antimalware Service Executable in Windows 11
Disabling the Antimalware Service Executable involves adjusting settings related to Windows Defender. Here’s a step-by-step guide on how to accomplish this task safely.
Step 1: Open the Windows Security App
Find and open the Windows Security app on your computer.
To open the app, type “Windows Security” in the search bar next to the Start menu and hit Enter. This app contains all the settings related to your computer’s security, including antivirus and firewall controls.
Step 2: Navigate to Virus & Threat Protection
Go to the “Virus & Threat Protection” section in the app.
Once you’re in the app, look for a shield icon labeled “Virus & threat protection” on the left-hand side. Clicking it will take you to all the controls you need to manage your antivirus settings.
Step 3: Manage Settings
Click on “Manage Settings” under the Virus & Threat Protection settings.
In this section, you’ll find a variety of options that control how Windows Defender operates. You can turn off real-time protection here, which will stop the Antimalware Service Executable from running.
Step 4: Turn Off Real-Time Protection
Toggle the switch to turn off real-time protection.
Simply switch the toggle to the “Off” position. But remember, this will only pause the service temporarily. Windows will automatically turn it back on after some time or upon restarting your computer.
Step 5: Adjust the Registry (Optional)
Edit the Windows registry to stop the service from turning back on.
This step is a bit more advanced and involves opening the registry editor. It is not recommended for beginners as it can affect other system functions if not done correctly. Only proceed if you are comfortable making system-level changes.
After following these steps, you’ll have temporarily disabled the Antimalware Service Executable, which should free up resources on your computer. However, remember that leaving your system unprotected can make you vulnerable to threats.
