For each phase, the laboratory awards up to 6 points for the performance of a product, which means that a maximum overall total of 18 points are achievable in the test. The last category primarily involves the test for false alarms. The lab puts all the solutions through tests in the categories of protection, performance, and usability. Among the security packages in the Windows 11 version were the following 19 security manufacturers: AhnLab, Avast (Free), Avast (One Essential), AVG, Avira, Bitdefender, F-Secure, G DATA, K7 Computing, Kaspersky, Malwarebytes, McAfee, Microworld, Norton, PC Matic,, Trend Micro, VIPRE Security and naturally Microsoft. In an initial test in the lab at AV-TEST under Windows 11, all new Windows 11 products of the manufacturers were put through comprehensive testing. 19 security packages under Windows 11 put to the test This test reveals that the reality looks different. The protection is deeply embedded into Windows 11, and according to Microsoft, it is only supposed to require little CPU power to do its job. This is intended to continuously protect the system against Trojans and other malware. At its core, the new Windows Defender Security Center consists of the Defender virus scanner. In the new Windows 11, Microsoft made several changes in terms of security.

Even the testers had expected that Microsoft’s internal protection, Windows Defender, would deliver similarly reliable performance as under Windows 10.

The initial test of Internet security suites using Windows 11 as a test system yielded some very interesting test results.
