How To Fix Antimalware Service Executable High CPU & RAM Usage

Before we dive into the solutions, let’s take a moment to understand what Antimalware Service Executable is and why it’s hogging your system resources.

Antimalware Service Executable, also known as MsMpEng.exe, is a crucial component of Windows Defender, Microsoft’s built-in antivirus and antimalware program. Its primary function is to scan your computer for threats such as viruses, malware, and spyware in real-time, ensuring your system remains secure. While this is undoubtedly an essential task, sometimes the Antimalware Service Executable can become a bit too enthusiastic, leading to high CPU and RAM usage.

Why Does Antimalware Service Executable Consume High Resources?

Several factors can contribute to the Antimalware Service Executable’s resource-hungry behavior. Let’s explore some of the common reasons:

1. Scanning Large Files

When Windows Defender scans large files or archives, it can temporarily spike CPU and RAM usage. This is particularly noticeable when dealing with sizable media files or folders.

2. Frequent Updates

Windows Defender frequently receives updates to its virus definitions and scanning algorithms. During these updates, the Antimalware Service Executable may consume additional resources to ensure your system is protected with the latest threat definitions.

3. Conflict with Third-Party Antivirus

If you have another antivirus or antimalware program installed alongside Windows Defender, conflicts can arise, leading to increased resource usage as both programs try to perform real-time scanning simultaneously.

Now that we have a better understanding of why this issue occurs, let’s explore some practical solutions to alleviate the high CPU and RAM usage caused by Antimalware Service Executable:

Schedule Scans

One effective way to reduce the impact of Windows Defender’s scans on your system’s performance is to schedule them for a time when you’re not actively using your computer. You can do this by following these steps:

1. Open Windows Security by clicking on the Windows Security icon in the system tray.
2. Click on “Virus & threat protection.”
3. Under “Current threats,” select “Manage settings” under “Virus & threat protection settings.”
4. Toggle off “Real-time protection.”
5. Scroll down to “Automatic sample submission” and toggle it off as well.
6. Exit Windows Security.

Exclude Folders and Files

If you have specific files or folders that you know are safe and don’t need constant scanning, you can exclude them from Windows Defender’s scans. Here’s how:

1. Open Windows Security.
2. Click on “Virus & threat protection.”
3. Under “Current threats,” select “Manage settings” under “Virus & threat protection settings.”
4. Scroll down to “Exclusions” and click on “Add or remove exclusions.”
5. Click on “Add an exclusion” and choose whether to exclude a file, folder, file type, or process.
6. Follow the on-screen instructions to specify the item to be excluded.

Disable Windows Defender

If you’re using a third-party antivirus program and want to rely on it exclusively for your computer’s security, you can disable Windows Defender. Here’s how:

1. Open Windows Security.
2. Click on “Virus & threat protection.”
3. Under “Current threats,” select “Manage settings” under “Virus & threat protection settings.”
4. Toggle off “Real-time protection.”
5. Scroll down to “Cloud-delivered protection” and toggle it off.
6. Scroll down further to “Tamper Protection” and toggle it off if necessary.

Please note that disabling Windows Defender will leave your system without built-in antivirus protection, so make sure you have a reliable alternative in place.

Check for Malware

Sometimes, the high resource usage attributed to Antimalware Service Executable could be due to an actual malware infection. It’s a good practice to run a full system scan with your antivirus program to ensure your system is clean from malicious software.

Conclusion

High CPU and RAM usage by Antimalware Service Executable can be a frustrating experience, but it’s often a sign that your computer is being actively protected against threats. By implementing the solutions mentioned above, you can strike a balance between system performance and security. Remember to regularly update your antivirus definitions and perform routine scans to keep your system safe without compromising its speed and efficiency.

We hope this guide has been helpful in resolving the Antimalware Service Executable high CPU and RAM usage issue on your Windows computer. If you have any further questions or encounter any challenges, don’t hesitate to seek professional assistance or reach out to Microsoft’s support resources.
