Know Everything About Antimalware Service Executable

Microsoft Defender Antivirus, earlier known as Windows Defender, is inbuilt into Windows 10. The background process of Microsoft Defender is “Antimalware Service.

The antimalware service executable, also known as MsMpEng.exe, may be consuming your resources if your computer is running slow.

While it is possible to disable it, it is recommended to be aware of the process’s goals and how it can really affect your PC’s security. 

What Is Antimalware Service Executable?

The antimalware service executable, as its names imply, helps in protecting your computer against malware and other virus threats. It is the background process for the built-in Microsoft Defender antivirus programme and is visible in Task Manager as MsMpEng.exe. Earlier, Windows Defender was known as the Microsoft Defender. It never stops performing in the background. It is in charge of everything a security system like Defender has to conduct, including scanning files for malware when you access them, running background system scans to look for malicious software, updating antivirus definition, and more. 

The antimalware service executable process requires more resources when doing scans and updates. All kinds of antivirus tools share this quality.

They frequently consume more resources when use is at its peak. After a scan or update, however, the usage does need to return to normal.

The Windows Security software that comes with Windows 10 and Windows 11 allows you to customise Microsoft Defender, run scans, and view its scan history.

The previous name of this software was “Windows Defender Security Centre.” Use the Start menu shortcut for “Windows Security” to start it. You may also choose “View Security Dashboard” from the context menu by right-clicking the shield symbol in the taskbar’s notification area, or you can go to Settings > Update & Security > Windows Security > Open Windows Security.

Is It Possible To Disable It?

If you don’t already have any antivirus software installed, we do not suggest turning off Microsoft Defender.In fact, it cannot be permanently disabled but You can turn it off temporarily. By doing this, the antimalware service executable will no longer run.

Microsoft Defender won’t be removed though.

You can disable it from the Start menu, launch the Windows Security programme, choose “Virus & Threat Protection,” click “Manage Settings” under the settings for that protection, and turn off “Real-Time Protection.” However, this is only a temporary solution, and if Microsoft Defender doesn’t detect any installed antivirus after a short while, it will re-enable itself.

Should You Stop the Antimalware Service Executable Service?

This is an important question, the antimalware service executable service helps you to protect your computer from malwares and other types or viruses but sometimes it may consume high resources which may create some big issues sometime which we will talk about in more details along with some solutions below.

Otherwise, you will face many other difficulties because of the malwares and viruses that will enter your system after you disable it, and if you looking for other antiviruses then make sure to get genuine anti virus software or you may face many other problems if you use any third party antiviruses so make sure to get one proper antivirus before disabling it.

Why Does the Anti-Malware Service Executable Consume a Lot of CPU?

This is the main problem of this program. If the antimalware service executable is using a large amount of CPU or memory resources, it is possibly scanning the system for malware.

Unfortunately, the scheduled Windows Defender scan also consumes a lot of CPU resources and slows it down your machine.

When your computer is idle and not in use, Microsoft Defender does a background analysis.

The CPU can be used by your computer even while it is idle to run updates or scan files when you access them. While you are using your computer, the background scans should not be running.
