How to Reduce the CPU Usage of Antimalware Service Executable

If you're experiencing high CPU usage on your computer, one possible culprit could be the Antimalware Service Executable. This service is part of Windows Defender, Microsoft's built-in antivirus program. While it's essential for keeping your system secure, it can sometimes consume a significant amount of CPU resources, causing slow performance and reduced efficiency. In this guide, we'll explore various methods to stop Antimalware Service Executable from using excessive CPU, allowing your computer to run smoothly without compromising on security.

Method 1: Adjusting Windows Defender's Scan Schedule

One way to reduce the CPU usage of Antimalware Service Executable is by adjusting the scan schedule of Windows Defender. By default, Windows Defender performs regular scans that can consume a lot of CPU resources. Follow these steps to modify the scan schedule:

• Open the Windows Defender Security Center by searching for it in the Start menu.
• Click on "Virus & threat protection".
• Under "Current threats", click on "Scan options".
• Click on "Windows Defender Offline scan" and toggle off the option for "Periodic scanning".

By disabling periodic scanning, you can prevent Windows Defender from running frequent scans that may overburden your CPU.

Method 1.1: Customizing Scan Settings

In addition to adjusting the scan schedule, you can further optimize the CPU usage of Antimalware Service Executable by customizing the scan settings. Here's how:

• In the Windows Defender Security Center, click on "Virus & threat protection".
• Under "Current threats", click on "Scan options".
• Choose the type of scan you want to customize (Quick Scan, Full Scan, or Custom Scan).
• Click on "Advanced scan".
• Toggle off unnecessary scan options such as "Files and folders" or "Removable drives".
• Save the changes.

By customizing the scan settings, you can exclude certain areas or file types from the scan, reducing the CPU load on Antimalware Service Executable.

Method 1.2: Using PowerShell to Change Scan Schedule

If you prefer using PowerShell commands to modify system settings, you can also change the scan schedule of Windows Defender with a few simple steps:

Set-MpPreference -DisableRealtimeMonitoring $true

This command temporarily disables real-time monitoring, effectively stopping Antimalware Service Executable from using CPU resources. Keep in mind that this is a temporary measure, and it's important to re-enable real-time monitoring after completing your tasks.

Method 2: Excluding Files and Folders from Windows Defender

If you notice high CPU usage specifically when accessing certain files or folders, you can exclude them from Windows Defender's scanning process. Here's how:

• Open the Windows Defender Security Center.
• Click on "Virus & threat protection".
• Under "Current threats", click on "Virus & threat protection settings".
• Scroll down to the "Exclusions" section and click on "Add or remove exclusions".
• Choose whether you want to exclude a file, folder, file type, or process. Click on the appropriate option.
• Follow the on-screen instructions to select the specific file, folder, or process to exclude.

By excluding certain files or folders, you can prevent Windows Defender from scanning them, thus reducing the CPU usage of Antimalware Service Executable.

Method 3: Use an Alternative Antivirus Program

If you've tried the previous methods and are still experiencing high CPU usage from Antimalware Service Executable, you may consider using an alternative antivirus program that is lighter on system resources. There are several reputable antivirus software options available that provide effective protection without significantly impacting CPU performance. Research and choose an antivirus program that suits your needs and preferences, and then follow the installation instructions provided by the software provider.

Method 4: Upgrade Your Hardware

In some cases, high CPU usage by Antimalware Service Executable may be due to outdated hardware that struggles to keep up with the demands of regular antivirus scans. Upgrading your hardware components, such as your processor or adding more RAM, can significantly improve system performance and reduce CPU usage. Consult with a computer technician or refer to your device's specifications to determine the compatibility of any hardware upgrades.

Conclusion

Antimalware Service Executable is an important component of Windows Defender, but it can sometimes consume excessive CPU resources, leading to performance issues. By adjusting the scan schedule, customizing scan settings, excluding files and folders, using alternative antivirus software, or upgrading your hardware, you can effectively reduce the CPU usage of Antimalware Service Executable and maintain a balance between system security and performance.

How to Optimize Antimalware Service Executable Performance

Antimalware Service Executable, also known as MsMpEng.exe, is a vital component of Windows Defender, responsible for protecting your computer from malware and other security threats. However, it can sometimes consume a significant amount of CPU resources, causing your system to slow down. To optimize Antimalware Service Executable performance and prevent it from using excessive CPU, follow these steps:

• Exclude certain files and folders: Adding specific files and folders to Windows Defender's exclusion list can help reduce the CPU usage of Antimalware Service Executable. Exclude non-executable files and folders that are not at risk of containing malware.
• Schedule scans during idle time: Change the default scan schedule to run when your computer is not in use. This will prevent Antimalware Service Executable from significantly impacting system performance while you are actively using your computer.
• Enable sample submission: By enabling sample submission, you allow Windows Defender to send suspicious files to Microsoft for analysis. This helps improve the effectiveness of the antivirus software and reduce the load on Antimalware Service Executable.
• Consider using alternative antivirus software: If Antimalware Service Executable continues to consume excessive CPU resources, you may want to consider using a different antivirus program that is less resource-intensive.
