Your computer’s performance takes a sudden nosedive, and you’re left wondering what’s causing it. If you’re a Windows 10 user, there’s a good chance that the culprit behind this slowdown is a process called Antimalware Service Executable, also known as MsMpEng.exe. This essential component of Windows Security is responsible for protecting your computer from malicious threats. However, at times, it can be a resource hog, leading to high CPU usage and sluggish performance. In this blog, we’ll unravel the mysteries of Antimalware Service Executable and provide easy-to-follow solutions to address its high CPU usage.

What is Antimalware Service Executable?

Before we delve into the issue of high CPU usage, let’s understand what Antimalware Service Executable is. In essence, it’s your computer’s shield against malware. This background process tirelessly scans files and programs to detect any signs of malicious activity. When it finds a virus or other threats, it takes prompt action, either removing or isolating the threat to keep your computer safe.

The Culprit: High CPU Usage

The heart of the problem lies in the constant background operation of Antimalware Service Executable. While it scans for threats, it also actively scans its own folder, “C:Program FilesWindows Defender.” This dual scanning process can exert significant pressure on your computer’s CPU, resulting in slow performance.

Creative Solutions for Everyone

Now, let’s explore some creative and user-friendly solutions to tackle the issue of high CPU usage by Antimalware Service Executable:

Solution 1: Prevent Self-Scanning

This method will reduce the burden on your CPU by preventing Antimalware Service Executable from scanning its own folder:

• Press the Windows key on your keyboard and open the Settings app.

• Click on “Update and Security,” then select “Windows Security.”

• Choose “Virus and threat protection” within Windows Security.

• Under “Virus & threat protection settings,” click “Manage Settings.”

• Scroll down to “Exclusions” and select “Add or remove exclusions.”

• Click “Add an exclusion” and choose “Folder.”

• Enter “C:Program FilesWindows Defender” into the editor and click “Select Folder.”

• A confirmation prompt will appear; make sure to click “Yes.”

This exclusion will ensure that Antimalware Service Executable no longer scans its own folder, easing the CPU’s workload.

Solution 2: Fine-Tune Scans

Another way to manage CPU usage is by rescheduling and optimizing Windows Defender scans:

• Press WIN + R to open the Run dialogue.
• Type “taskschd.msc” and click “OK” to open Task Scheduler.

• Expand “Task Scheduler Library,” “Microsoft,” and “Windows.”

• Scroll down and select “Windows Defender.”
• Right-click on “Windows Defender Scheduled Scan” and choose “Properties.”

• Uncheck “Run with highest privileges” in the General tab.
• In the Conditions tab, uncheck all options.
• Switch to the Triggers tab and click “New” to schedule when Windows Defender runs scans based on your preferences.
• Restart your computer to apply these changes.

By optimizing the scan schedule, you can ensure that Antimalware Service Executable doesn’t overtax your CPU.

Closing Thoughts

Antimalware Service Executable plays a pivotal role in safeguarding your computer from malware. While its high CPU usage can be vexing, these user-friendly solutions should help you restore your computer’s performance. Remember that a well-protected computer is a necessity in today’s digital landscape, and with these creative solutions, you can have both protection and performance.
