What is Antimalware Service Executable and why is its CPU usage high?
Antimalware Service Executable, more commonly known as msmpeng.exe, is an indispensable component of Windows Security which works continuously behind the scenes of your computer. It acts like a vigilant warrior, ensuring the real-time protection of your system against malicious intrusions, thanks to its careful analyzes of files and programs carried out regularly. This process, similar to a guard tour, detects any virus or attack with harmful intentions, in order to exterminate them or isolate them in quarantine.
However, the efficiency of this digital warrior comes at a cost: it can sometimes be very CPU intensive. Indeed, its operation can lead to high CPU consumption, thus significantly slowing down the performance of your computer under Windows 10. This phenomenon is due to the analysis operation which requires a lot of resources, more when confronted with large files, or a multitude of files simultaneously.
It is also necessary to take into account other factors that can accentuate this high CPU usage. For example, outdated antivirus definitions or conflicts with other security software can be sources of this overconsumption. Thus, an up-to-date antivirus and harmonious management of your security software can contribute to better performance of your system.
By having a better understanding of how msmpeng.exe works, you will be able to better anticipate and manage its impact on your computer's resources. Thus, despite its sometimes high CPU consumption, Antimalware Service Executable remains an essential player for the real-time protection of your system against malware.

How to optimize CPU usage by Antimalware Service Executable?
The essential role of Antimalware Service Executable pushes us to address the crucial question of its optimization in order to ensure optimal security without harming the performance of your personal computer. First of all, it is essential to note the major importance of performing regular updates of your antivirus definitions. The latter, well beyond a simple recommendation, are a real imperative to guarantee an effective and precise analysis of possible threats.
Additionally, scheduling these analyzes is a smart strategy that should be considered. By setting periods of low usage on your computer as your scanning window, you can ensure optimal performance when you need it most. It is therefore possible to take full advantage of the functionality of your machine without suffering the inconvenience of increased CPU usage linked to Antimalware Service Executable.
However, the sophistication of Antimalware Service Executable allows advanced users to go even further in optimization. Excluding certain specific files or folders from scanning promises a noticeable reduction in the use of the CPU. This can be particularly beneficial for large files or programs that are frequently opened and closed.
Despite all these efforts, the problem may still persist. At this point, the option of using another antivirus software can be considered. The market offers many competent alternative software, some more efficient and less CPU-intensive than the Antimalware executable service. Exploring these alternative solutions can be the last resort to optimize CPU usage while ensuring complete and robust protection for your computer.

High CPU consumption by Antimalware Service Executable
Antimalware Service Executable, one of the essential components of the so-called Windows Defender, by constantly operating in the background and analyzing various programs and files in real time, can lead to significant CPU usage. The irony is that it even analyzes its own file, which increases its consumption of CPU resources.
That said, few people realize that the Antimalware Service Executable reviews its own files in its security scans, which results in increased CPU usage. Although it may seem counterintuitive, stopping this action could ease the load on your CPU. However, it is crucial to understand that this could also disable real-time protection.
There are various strategies to minimize this CPU consumption. One such approach involves reprogramming Windows Security scans. It is important to emphasize that this approach will not increase the frequency of scans, but will allow, on the one hand, to organize them according to your convenience and, on the other hand, to reduce the load of the Antimalware Service Executable on the CPU. .
Another solution is to restrict the Antimalware Service Executable from examining its own folders. By doing this, we not only reduce CPU usage but also avoid deactivating real-time protection.
Therefore, optimize CPU usage by the Antimalware Service Executable requires a thorough knowledge of its functionality as well as a clear understanding of your IT security needs. It is essential to keep in mind that any compromise made to save CPU resources could potentially expose your system to threats. However, by approaching these issues in a balanced way, it is entirely possible to benefit from robust protection without excessively taxing the CPU.

Solution to prevent Antimalware Service Executable from scanning its own folder
The Antimalware Service Executable, a crucial component of Windows Defender, is inherently programmed to run tirelessly, constantly monitoring your computer's activities. Its vigilance, although necessary for the security of your system, can sometimes result in high consumption of your CPU, thus affecting the general performance of your machine.
However, there is an often overlooked tip to limit the impact of this service on your processor: prohibit it from analyzing its own file. Indeed, excluding the Windows Defender folder from the Antimalware Service Executable's scope of action can be very useful in reducing its CPU usage.
To do this, go to the “Windows Security” application before clicking on “Virus & threat protection”, then on “Manage settings”. Within this interface, look for the “Exclusions” option in order to add the path to the Windows Defender folder, generally located at the following address: “C:\Program Files\Windows Defender”.
Once this operation is completed, Antimalware Service Executable will no longer scan its own folder, which should lighten the load on your CPU significantly. Note that this method, although effective, should be used with caution. Make sure your system isn't already infected with malware before proceeding, as this could potentially leave the virus roaming free in the Windows Defender folder.
Also remember that not all means are good for optimizing your computer. The security of your system should always be your priority. Even though Antimalware Service Executable's resource consumption can sometimes be annoying, remember that it is necessary to provide effective real-time protection against malicious threats.

Two methods to reduce CPU usage of antimalware service executable
Before we dive into the nitty-gritty, it's essential to note that every computer has a unique architecture. Therefore, the effectiveness of the two methods we are about to review may vary depending on your computer model, configuration, resources, and even your typical usage. However, the need to reduce CPU usage byanti-malware service executable remains a universal concern for all Windows users.
The first method is to schedule analysis times for your files and software. It's simple, head into Windows Defender settings and schedule scans for times when you're not actively using your computer. For example, late at night or early in the morning. Please note that this method may be ineffective if the computer is turned off during the scheduled times. So it's best to schedule the scan during hours when your computer is on but not in use.
The second method is configuring your antivirus exclusion settings. Here you can exclude certain files, folders, or even specific processes, thereby relieving the workload of the antimalware service executable. However, this method should be used with caution. Excluding sensitive folders can indeed leave your system vulnerable to malware attacks.
If despite the application of these two methods, the CPU consumption remains high, then deactivate the windows anti-virus service can be considered. But beware, having a solid alternative to replace Windows Defender is crucial to maintain your system's level of protection against malware.
Never forget, the security of your system should always come first. So, before making any changes, make sure you have weighed the pros and cons carefully. Your computer will thank you!
