Microsoft Defender is a built-in anti-virus function in Windows, so compared with other third-party anti-virus software, many people should think that it should occupy the least system performance. In fact, it may be completely the opposite. Recently, a foreign security testing agency released the latest performance test report. A total of 17 antivirus software were tested. Microsoft Defender actually has a great impact on the performance of the PC system, and it ranks second to last.
Foreign test institutions found that Microsoft Defender has a great impact on PC system performance
Recently, the foreign security testing agency AV-Comparatives announced the performance test results in April 2022 to understand how much the current antivirus software on the market affects the system performance. The test platform is Intel i3 processor, 4GB RAM and SSD hard disk. The operating system version is equipped with the latest Windows 10 21H2 64-bit. In addition to the PCMark 10 running points, there is also AV-Comparatives’ own test process, including the following activities:
- file copy
- save/unarchive
- Install/Remove Apps
- start the application

Microsoft Defender ended up only ahead of Total Defense, with an impact score of 24.6, which earned it only one star:
This also means that if you do not want antivirus software to affect too much system performance, it is recommended to install third-party antivirus software.
Of course, in this era of increasingly powerful computer hardware, this effect may not be felt. For those who care, you can try to use Microsoft Defender first, and switch to third-party antivirus software for a while. Is there any difference.
