ByMia Carla 2019-05-17 9516

Despite its name similarity, Antimalware Service Executable has nothing to do with Emsisoft Anti-Malware. It is a process required for the Windows Defender service - an integral part of Windows 10. Unfortunately, he's known more for his excessive CPU usage, which sometimes causes your computer to slow down.

How to disable CPU brake

If you use Windows Defender and the CPU is unusually often and long-stressed, we have good news for you: The problem can be solved easily.

In this article, we'll explain in simple steps how to make sure your system runs smoothly and is not thwarted by Antimalware Service Executable .

Antimalware Service Executable MsMpEng.exe - What is it?

Are you using Windows Defender as your antivirus program on your computer? Then open Windows Task Manager (Ctrl + Shift + Esc or Start Menu> Task Manager) and scroll through the Processes list. There you will see the process "Antimalware Service Executable" and the associated msmpeng.exe.

This process allows Windows Defender to continuously monitor your computer for possible threats to protect it in real-time against malware and cyber-attacks. However, this process can overload the CPU excessively.

Another feature of Windows Defender that can affect system performance is the Full scan option . When activated, all files on the computer are checked. However, during the scanning process, the option uses all available system resources of the CPU. As a result, there are disruptions such as the computer only reacting very slowly and with delays or getting stuck.

That antivirus programs consume system resources when scanning is completely normal. Unlike most solutions, Windows Defender, however, has a fairly strong thirst for performance. The service is already notorious for its long-lasting high CPU usage. In addition, scans are executed when you turn on the computer to quickly retrieve e-mails or check the bus timetable on the Internet.

Although this might be frustrating for the moment, be sure to disable the Windows Defender after installing another security solution. It may be the only way to protect your computer from the bad guys. So let the program do its work first and fix any threats. Afterwards, you can try the following tips to avoid such delays in the future:

Solution 1: Change the schedule of Windows Defender

For most users, Antimalware Service Executable typically consumes the most memory when Windows Defender performs a full scan. This problem is easy to fix. The scans only need to be scheduled for a time when you are not very bothered by this CPU usage.

●   Open the Start menu , enter "Task Scheduler" and click on the top result to start the program.

●   In the left navigation area, double-click Task Scheduler Library . Expand each folder to navigate to the following location: Task Scheduler Library \ Microsoft \ Windows \ Windows Defender

●   If you open the "Windows Defender" folder, double the middle area on Windows Defender Scheduled scan.

●   Open the Conditions tab , deselect all options, and click OK . This removes all scheduled scans.

●   To keep your computer protected, you need to create new scans. However, these can be set up so that your system performance is not affected as much. Double click again on Windows Defender Scheduled scanning, open the "Trigger" tab and click "New ...".

●   Create a new scan schedule that suits you best. When choosing options, keep a good balance between protection and system performance. As a guideline, we recommend (at least) weekly scans at a time that does not disturb the higher CPU usage.

●   Repeat the process for the other three services (Windows Defender Cache Maintenance, Windows Defender Cleanup, Windows Defender Verification), which appear in the Task Scheduler Library \ Microsoft \ Windows \ Windows Defender folder .

Solution 2: Add Antimalware Service Executable to Windows Defender Exclusion List

While scanning, Windows Defender checks every single file on the computer - including its own. This can sometimes lead to unwanted interactions or loops, a common cause of system delays. You can avoid this by telling Windows Defender to ignore itself during a system scan.

●   Press Ctrl + Shift + Esc to open Task Manager.

●   Look for "Antimalware Service Executable" in the process list . Right-click on the process and select "Open File Path" .

●   The address bar displays the full path of Antimalware Service Executable. Click the address bar and copy the full path .

●   Open the Start menu and enter "Windows Defender". Click on the top result to start the Windows Defender Security Center.

●   Click Virus & Threat Protection, then Virus & Threat Protection Settings .

●   Scroll down to the "Exclusions" item and then click Add or Remove Exclusions . In the next screen, click on "Add exclusion" and select "Folder". Now add the path to the Antimalware Service Executable (MsMpEng.exe). Click "Open" and the folder will be excluded from the scans.

Solution 3: Disable Windows Defender

The first two solutions did not help and you would like to disable Windows Defender completely? Then be sure to install an effective third-party anti-malware solution first. Otherwise you will not be protected against cyber attacks.

●   Press Windows key + R to open the Run dialog.

●   Type regedit and then click OK to open the Registry Editor.

●   Double-click each folder in the left navigation pane to navigate to the following path: HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows Defender

●   If you see the DisableAntiSpyware entry , double- click it and set its value to 1. If the DisableAntiSpyware entry does not exist, right-click in the empty area of ​​the Registry Editor and select New> DWORD Value (32-bit ) ". 
Enter DisableAntiSpyware as the name for the new value . Double-click on it and set its value to

Solution 4: Check for malware infestation

It's quite possible that something worse may be the reason why Windows Defender slows down your system performance. There are many different types of malware that can interfere with the smooth and secure operation of your computer. Be sure to check your PC for malware by performing a full system scan with a recognized and resource-efficient anti-malware solution such as Emsisoft Anti-Malware .

Windows Defender is a useful tool that is included for free in your operating system. Unfortunately, it can also be quite a burden for your CPU. By following the tips outlined here, you can bring Antimalware Service Executable under control and your computer back to full speed.

We wish you a nice (malware-free) time.
