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.
