Que Es Antimalware Service Executable Windows 11

If you try to make antimalware service executable consume less CPU with the 2 methods explained in this article and there seems to be no progress, you should try to disable your Windows Security program permanently.
I can't disable the Microsoft Antimalware service (MsMpSvc/MsMpEng.exe). I tried using services.msc, but the Startup Type drop-down is grayed out and I can't change it to Disabled nor stop the service. I also tried msconfig, but when I click Apply, the service gets enabled again. I even tried net stop msmpsvc and got system error 5 (access denied).
The best way to disable the Defender is to run regedit.exe, go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender, take ownership of this registry key (inside regedit.exe or via the 3rd party tool RegOwnershipEx) and set the values DisableAntiSpyware and DisableAntiVirus both to 1.
Windows Defender/Microsoft Security Essentials is very tightly knit into the operating system in order to provide more security. It's best to disable it through the natural means than trying to cut it out piece by piece.
Go to your control panel, and select the entry for your Microsoft Antivirus. It might be listed as "Windows Defender" depending on your update history. Look in the 'settings' section in the Antivirus GUI for a "disable"
Depending on how updated your Windows Defender/MSE is, and how updated you received the program, these steps may vary, but the general idea is the same: disable it the way they provided you, not by trying to be crafty.
This will launch Registry Editor with Trusted Installer privileges. Be extra careful because now you will be able to change or delete ANY registry key which means if you delete or change the wrong one you will hose your system.
To stop the Microsoft Antimalware Service you need TrustedInstaller permissions. One way to gain those is using the RunAsTI tool. When you run that it opens a command prompt with TrustedInstaller privileges, from which you can stop it with net stop:
If you want to disable the service permanently, you can run SubInACL /service MsMpSvc /grant=Administrators=F from that TrustedInstaller command prompt to grant Administrators Full Control over the service, then stop and disable it in the Service MMC snap-in as usual. Note that if you ever start it again it will reset its own permissions, so TrustedInstaller privileges will be required again to stop it.
Located the executable for Windows Defender, using open file location in Task Manager. For me it was located at C:\ProgramData\Microsoft\Windows Defender\Platform\4.18.2107.4-0 and was called MsMpEng.exe
Antimalware service executable is a part of the Microsoft Defender antivirus included with Windows. It scans files and processes in the background and updates virus definitions. You can disable it completely if you install another antivirus program to replace Microsoft Defender.
Windows 10 includes built-in Microsoft Defender Antivirus, formerly known as Windows Defender. The "Antimalware Service Executable" process is Microsoft Defender's background process. This program is also known as MsMpEng.exe, and is part of the Windows operating system.
This article is part of our ongoing series explaining various processes found in Task Manager, like Runtime Broker, svchost.exe, dwm.exe, ctfmon.exe, rundll32.exe, Adobe_Updater.exe, and many others. Don't know what those services are? Better start reading!
Microsoft Defender, formerly known as Windows Defender, is part of Windows 10 and is the successor to the free Microsoft Security Essentials antivirus for Windows 7. This ensures that all Windows 10 users always have an antivirus program installed and running, even if they haven't chosen to install one. If you have an out-of-date antivirus application installed, Windows 10 will deactivate it and activate Microsoft Defender for you. Windows 11 includes the same Microsoft Defender antivirus software, too.
The Antimalware Service Executable process is Microsoft Defender's background service, and it always remains running in the background. It's responsible for checking files for malware when you access them, performing background system scans to check for dangerous software, installing antivirus definition updates, and anything else a security application like Defender needs to do.
You can configure Microsoft Defender, perform scans, and check its scan history from the Windows Security application included with Windows 10 and Windows 11. This application was formerly named the "Windows Defender Security Center."
To launch it, use the "Windows Security" shortcut in the Start menu. You can also right-click the shield icon in the notification area on your taskbar and select "View Security Dashboard," or head to Settings > Update & Security > Windows Security > Open Windows Security.
If you see the Antimalware Service Executable process using a large amount of CPU or disk resources, it's likely scanning your computer for malware. Like other antivirus tools, Microsoft Defender performs regular background scans of the files on your computer.
It also scans files when you open them, and regularly installs updates with information about new malware. This CPU usage could also indicate that it's installing an update, or that you just opened a particularly large file Microsoft Defender needs some extra time to analyze.
Microsoft Defender generally performs background scans only when your computer is idle and isn't being used. However, it may still use CPU resources performing updates or scanning files as you open them, even while you use your computer. But the background scans shouldn't run while you're using your PC.
We do not recommend disabling the Microsoft Defender antivirus tool if you don't have any other antivirus software installed. In fact, you can't disable it permanently. You can open the Windows Security application from your Start menu, select "Virus & Threat Protection," click "Manage Settings" under Virus & Threat protection settings, and disable "Real-Time Protection." However, this is just temporary, and Microsoft Defender will re-enable itself after a short period of time if it doesn't detect other antivirus apps installed.
Despite some misleading advice you'll see online, Defender performs its scans as a system maintenance task you can't disable. Disabling its tasks in the Task Scheduler won't help. It will only permanently stop if you install another antivirus program to take its place.
If you do have another antivirus program installed (like Avira or BitDefender), Microsoft Defender will automatically disable itself and get out of your way. If you head to Windows Security > Virus & threat protection, you'll see a message saying "You're using other antivirus providers" if you have another antivirus program installed and activated. This means that Windows Defender is disabled. The process may run in the background, but it shouldn't use CPU or disk resources attempting to scan your system.
However, there is a way to use both your antivirus program of choice and Microsoft Defender. On this same screen, you can expand "Microsoft Defender Antivirus options" and enable "Periodic scanning." Defender will then perform regular background scans even while you're using another antivirus program, providing a second opinion and potentially catching things your main antivirus might miss.
If you see Microsoft Defender using CPU even while you have other antivirus tools installed and want to stop it, head here and ensure the Periodic scanning feature is set to "Off." If it doesn't bother you, feel free to enable Periodic scanning---it's another layer of protection and additional security. However, this feature is off by default.
We haven't seen any reports of viruses pretending to imitate the Antimalware Service Executable process. Microsoft Defender is itself an antivirus, so it should ideally stop any malware attempting to do this in its tracks. As long as you're using Windows and have Microsoft Defender enabled, it's normal for it to be running.
I generally do not have any issues with Microsoft Security Essentials. It just works, and does its job quite well. From time to time I notice some weird issues on my client computers, where MsMpEng.exe (Antimalware service executable) is using way too many and high resources and cpu time. (extra large amounts of memory and cpu time may even be 100%)
That post says to exclude some directories from your scanning. I have since found that, in the newer version of Microsoft Security Essentials, there are some options that have also helped. We mainly want to tell MSSE that we only want to scan if the computer is not in use. I also set to Limut CPU usage.
Windows Defender uses the Antimalware Service Executable or MsMpEng (MsMpEng.exe) process to execute its functions. However, a number of Windows users have noted that the Antimalware Service Executable (MsMpEng) sometimes shows high CPU usage.
Antimalware service executable (MsMpEng) is a Windows Security process that executes real-time protection against malware. Also known as msmpeng.exe, the antimalware service executable Windows process runs in the background, so it can scan files and programs from time to time. When an antimalware service executable detects a virus or other malicious attacks, it deletes them or quarantines them.
The MsMpEng.exe runs the Windows Antimalware Service Executable to enable Windows Defender to monitor your PC for potential threats continuously. When it runs, the Antimalware Service Executable also ensures that Windows Defender provides real-time protection against viruses, malware, and cyberattacks. It's closely tied to Windows Defender's real-time protection feature against malware and cyberattacks.
However, many user reports on Microsoft support forums have shown that sometimes the MsMpEng.exe can also cause disproportionately high CPU and Memory usage. Some users also reported experiencing MsMpEng.exe high disk usage.
