Antimalware Service Executable file
Antimalware Service Executable file
Your PC experiences unexpected CPU spikes and unusual behavior in Task-Manager. It seems the Antimalware Service is consuming a lot of resources, entering low power mode intermittently, but not showing it clearly. The issue resets after closing Task-Manager. As an administrator, you're blocked from accessing it. Windows Security reports no threats. Consider checking for background processes or malware that might be interfering.
When the Antimalware Service Executable runs with high CPU or disk activity, it’s probably checking your system for threats. Similar to other antivirus programs, Windows Defender conducts routine background scans of your files and updates its database with new malware information. Such heavy usage might also happen when installing an update or when opening a very large file that needs more time for analysis. Windows Defender usually only runs these scans when your computer is idle and not in use. Still, it can consume CPU while updating or scanning during file openings, even while you’re using the PC. Background scans are normal for any security software, as they require system resources to protect your device.
You can adjust your power plan in Windows or review your Windows Defender preferences to prevent this from occurring again. This is why I’m using an unmodified version of Windows. I’m running the Ghostspectre edition. You can find more details on YouTube.
