AV-Comparatives: Microsoft Defender Has a Big Impact on System Performance
Security research and testing company AV-Comparatives has released the results of its April 2022 performance test. The test analyzed the impact of antivirus solutions on system performance on Windows devices.
The company ran a number of tests on a fully patched Windows 10 version 21H2 device. The device was powered by an Intel Core i3 processor, 4 gigabytes of memory and Solid State Drive hard drives.
The tests included common operations and activities on the device, including copying, checking in, and extracting files, installing or uninstalling apps, browsing sites, and launching apps. apps. Additionally, researchers conducted benchmark tests in PC Mark 10 Professional to gauge the impact of the system during real-world use.
The ranking system assigned a slow, poor, fast, and very fast rating to each of the products in all test categories. The four ratings reveal how much better or worse a product is compared to other tested programs.
Only one antivirus solution, K7, scored very fast in all test categories. ESET, G Data and Panda had a single “fast” rating while all others were rated as “very fast”.
Microsoft Defender did not perform well in testing. It ranked second to last in the test, only Total Defense had a higher impact on system performance than Microsoft’s product.
Although Microsoft Defender received several “very fast” ratings when launching apps, browsing websites, and downloading files, it received the worst “slow” score in the first copy test. of files. It performed better on subsequent runs, earning a “very fast” rating in this test category.
Microsoft’s security product scored “poor” in the app install test, which it shared with Total Defense. All other products scored “fast” or “very fast” in the test.
Microsoft Defender ranked second to last in the test. It did not perform well in two of the test categories, which had a significant impact on system performance while those specific tasks were performed on the test system. The benchmark test result puts it in the middle of the apps tested.
Tests were run on a single low-power system and results may differ on other systems. Faster systems may see less performance impact when these activities and operations are performed. A comparison with other low-power systems might have given a clearer picture of the performance impact.
Microsoft Defender also did not perform well when testing AV-Comparatives’ offline scanning capabilities.
