Microsoft finally has something to rejoice about. If you’re wondering what this is all about, the latest antivirus product test rankings for both AV-TEST and AV-Comparatives were recently released. In the AV-TEST results, Microsoft came in last place due to Defender’s major impact on Windows 11 system performance, which was quite a contradiction to how Defender previously performed in the Windows 10 tests. And it was doubly bad news for Microsoft, as AV-Comparatives also placed Microsoft in last place on the podium due to very poor results in the October 2022 performance test conducted on Windows 10.
Things are looking good again for Microsoft in AV-Comparatives’ real-world protection test. Unlike the previous performance test, which measured the performance impact of an antivirus program, the Real-world test measures an anti-malware solution’s ability to detect and block real threats. The test also measures the number of false positives, even user dependent. These are quantified by the FP score and the higher the score, the worse. User-dependent false positives are assigned half points.
You can view the FP scores of all tested products, including Microsoft’s, which has seven false positives:
Next, we have the protection rate, which measures how many malicious sample test cases have been successfully blocked by each product. Out of a total of 626 test cases, Defender was able to detect and block 623:
Finally, we have the AV-Comparatives certifications and it is expected that Microsoft received the ADVANCED+ rating. All in all, it seems that ESET did the worst in terms of detections, as it was compromised seven out of 626 times. However, Malwarebytes got the worst certification, TESTED, due to the highest number of false positives on top of six compromises.
