The AVC score has the full mark of 90 while the PC Mark score is out of 100. File copying, archiving, and app installations seem to be the Achilles' heel of Defender as they have the greatest performance impact according to AV-Comparatives' test, and once again, it is in line with what AV-TEST also found, and extremely similar results were also seen in AV-Comparatives' own previous ranking.ĪV-TEST graded the different anti-virus products using its own AV-C or AVC score as well as a PCMark score. In the case of the latter, Microsoft Defender was found to bog down a user's system the most (according to a quantitive metric) out of all the tested products. The findings of AV-TEST seem to match AV-Comparatives' latest test results as well. This is quite contrary to how Defender generally does on Windows 10 in AV-TEST's assessments. In fact, it only managed to secure the last place where it shared the position with another product. And surprisingly, the overall performance of Microsoft Defender turned out to be far worse than expected. This was the first time that AV-TEST evaluated the performance of such products on a test bench running Windows 11. Earlier today, AV-TEST, which is a reputed anti-malware assessment firm, released its l atest rankings for anti-virus products for home users.
