Antimalware Service Executable (also known as MsMpEng. exe) is a security program related to the Windows Defender program. It’s the background service that runs the protection module of Defender and helps detect, quarantine and remove malicious programs such as ransomware, viruses, spyware, and other potentially unwanted software.
It is always running to protect the computer from viruses, malware, and other threats. By constantly monitoring for potential threats in the background, it ensures the computer is secure and running optimally.
MsMpEng. exe can also scan files that are downloaded from the internet or sent as email attachments to protect from malicious programs. It evaluates files against a set of definitions and rules that Microsoft updates every day, making sure the security is always up to date.
By monitoring any downloads, it helps detect ransomware, adware, and other malicious programs before they can damage the computer.
Although it’s running in the background, it’s not a major resource hog and shouldn’t be the cause of any major performance issues. However, if it is taking up a majority of the system resources, then it could be due to a virus or other malicious software on the computer.
In these cases, it’s important to scan the computer with an antivirus and perform a thorough cleaning to ensure the system is safe and secure.

The best way to stop McAfee from using too much of your CPU is to ensure you are running the latest version of the software. Earlier versions had a known issue with CPU usage, so the current version should be more stable and use fewer resources.
If you are already running the latest version and the CPU usage is still high, you should consider disabling some of the features that could be using more CPU, such as the real-time scanning and auto-scheduling.
If you are still not seeing the desired resource usage, you can also try restarting your computer and reinstalling the software. If the issue persists, you can also contact McAfee support team for more guidance.
Why is Windows Defender using so much memory?
Windows Defender is a built-in security tool in Windows operating systems, providing an extra layer of protection against malicious software. As an antimalware solution, it runs in the background and scans system files as well as network and internet connections, which can take significant resources in terms of memory and processing power.
Depending on the size of the hard drive and the number of files it needs to scan, Windows Defender can certainly use a lot of memory. Additionally, if other applications are running at the same time, it can cause even more demand.
In addition to scanning, Windows Defender also stores its definitions in memory, which can result in an additional strain on the memory resources. To reduce the memory consumption of Windows Defender, you can try running a full scan at a convenient time once a week or disable real-time scanning for selected time periods.
