Maybe we can say that Microsoft defender has had a hard time recently. A few days ago, it was reported that defender for endpoint caused various problems on the customer's windows 10 system Now, there is another bad news. The test results show that Microsoft's built-in anti malware products will have a serious performance impact on the windows system on poorly configured computers
In the rating of av-c, defender can barely get the "standard" rating because it ranks second to last with total defense anti virus in the evaluation. This test is mainly conducted for the following anti malware products:
- Avast Free Antivirus 22.3

The actual test is to use the latest windows 10 21h2 64 bit system equipped with Intel Core-i3, 4GB memory and SSD。 I3 and 4GB memory are used to simulate typical low-end computers, which are generally most affected by anti-virus programs.

The total score obtained in the above test is called "av-c score". In addition to the actual tests listed above, the synthetic benchmark of PC mark 10 professional test suite was also run.
The following is the performance of all products in the test. The picture above shows the performance of av-c, and the picture below shows the total score, including the score of PC mark.
This column basically represents the difference between the total score obtained and the full score of 190. Therefore, the greater the impact score, the greater the impact of anti malware programs on the performance of the test system. For example, if we take Microsoft defender as an example, its impact score is 24.6, which means that its score is 24.6 points less than the full score of 190 points, that is, 165.4 points.
