Antimalware Service Executable High CPU/Disk Usage
Windows 10 includes Windows Defender, Microsoft’s built-in antivirus. The Antimalware Service Executable process is Windows Defender’s background process. This program is also known as MsMpEng.exe and is part of the Windows operating system.
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 Windows Defender needs to do. That’s why it’s very likely to take up huge disk, memory, RAM and even network bandwidth, draining computer resources, especially after getting a Windows 10 update.
