Why Does It Take High CPU Usage

It is as simple as calculating two plus two. It scans all your files and software in the background to monitor any suspicious malware or virus threats.

However, it does not scan only your files and software but also its files. Therefore, it eats up all CPU to provide comprehensive details. When it runs on a high CPU, you may face apps crash, lags, hang, and other issues.

In this contrast, it is perfectly fine to take CPU or another resource to provide a complete virus scanning. Inconveniently, you can’t use your system when all CPU energy goes into Microsoft Defender. One of the best practices is scheduling the scanning process to accomplish everything systematically.
