What is MsMpEng.exe Antimalware Service Executable

What is MsMpEng.exe Antimalware Service Executable? Anti-Malware Service Executable is the name of the process MsMpEng exe antimalware service executable disable anti-malware service that is used by the Windows Defender program.

The service that is associated with this program is Windows Defender Service. The two most common reasons for a high CPU usage are real-time functions, which constantly scan files, connections and other related apps in real-time.

Is it a virus? We have not seen a virus report pretending to emulate the “executable service antimalware” process. Windows Defender itself is antivirus, so the malware should stop in the ideal case. As long as you use Windows and activate Windows Defender, it is normal to run.

If you are really worried, you can always scan with other anti-virus apps to ensure that no malicious things are running on your PC.

Users of Windows 7, 8, 8.1 and 10 in the sea know that every time they open their device and connect them to the network or via a Bluetooth connection, anti-malware executable began to consume the largest part of the CPU, which is about 60-70%. This keeps them fixed, what to do to avoid such situations. A few months ago, when I was using Windows 8, I was also confronted with this problem.

How to repair it – MsMpEng.exe antimalware service executable high CPU usage?


1. First, make sure you do not have any other antivirus programs installed on your computer before you resolve the high CPU usage MsMpEng.exe.

2. If you are using Windows XP then you should remove Microsoft Security Essentials as it is no longer supported in Windows XP.

Step 1: Check and clean your computer from malware.

Step 2: Uninstall and reinstall Microsoft Security Essentials.

Step 3: Close the MsMpEng.exe file from scanning.

Step 4. Re-schedule the MSE scan time – Disable Microsoft Security Client.

Step 5: Install other antivirus programs on your computer.

Then next is the possible full scan feature that scans all files when the computer wakes up from sleep or when connected to a network, or when it is scheduled to run every day. Little can be understood here, when the scan is complete, your system is often delayed by delays, trailer, and access or response of the input or interaction with the system since the CPU is abducted by the defender.

Do not be afraid or lose patience here, instead of running it and scanning it, wait a few minutes and if there are many files etc, it can take some hours so let it go and quit what is done for the sake of protection once , the CPU will release the CPU and USE will be normal. However, Full Scan can be done only occasionally and not every day that I have seen with most users is that they have scheduled scan function when the computer wakes up from sleep, or is connected to a network, or when the scan should run every day, This issue may also apply to users who are using Windows 7 and Microsoft Security Essentials. The method is very similar, if not the same.
