Did you know that the antimalware service executable, also known as MsMpEng.exe, is a process that runs in the background on your PC to help protect it from malware and other security threats? This service is a crucial component of Windows Defender, Microsoft’s built-in antivirus program that comes pre-installed on Windows operating systems.

Initially introduced in Windows Vista, Windows Defender has evolved over the years to become a powerful tool for keeping your computer safe from malicious software. The antimalware service executable plays a key role in this defense mechanism by constantly scanning files, monitoring processes, and performing other security tasks to ensure the safety of your system.

One common issue that users may encounter with the antimalware service executable is high CPU usage. This can slow down your computer and cause performance issues. One effective solution to this problem is to schedule regular scans during off-peak hours or to exclude certain files and folders from being scanned, which can help reduce the workload on the service.

Another issue that may arise is frequent freezing or crashing of programs due to Windows Defender scanning files in the background. To address this issue, you can adjust the scan frequency or set specific times for scans to run when you’re not actively using your computer. This can help prevent interruptions and improve overall system performance.
