Microsoft Defender, the default security solution for modern versions of the Windows operating system, has performed well in recent antivirus tests by independent organizations such as AV-Comparatives. In 2019, it was revealed that Windows Defender already had more than 50% market share on Windows.
The latest test by AV-Comparatives confirms Microsoft Defender’s high detection and protection rate, but also shows that the program’s offline detection rate is weaker than the detection rate of most competing antivirus solutions.
According to the results of the test, Microsoft Defender had one of the worst offline detection rate scores; It managed to detect 60.3% of all threats on offline devices. Only Panda Free Antivirus, with a detection rate of 40.6%, and Trend Micro Internet Security, with a detection rate of 36.1%, performed worse in the offline detection test.
According to the test, the remaining 14 antivirus solutions offer better offline detection rates. Bitdefender and Total Defense Essential Antivirus, the latter using the Bitdefender engine, detected 97.8% of all threats in tests. Many antivirus solutions detected over 90% on offline devices.
Microsoft Defender performed better on internet-connected devices. The default Windows security solution caught 98.8% of all threats and had a protection rate of 99.96%, good test results but not the best result of all tested products.
AV Comparatives switched from reporting detection ratings to reporting detection and protection ratings for all products tested. Antivirus programs may not always detect inactive malware samples, but they may detect them when they are active. this explains the higher percentage of protection rates in the table.
Avast and AVG, the latter owned by Avast, achieved 99.5% and 99.98%, respectively, McAfee 99.3% and 99.97% detection and protection rates, and G Data 98.6% and 99.99%, respectively.
Microsoft Defender had 4 false positives in the test. Five products had fewer false positives, one the same result as Microsoft. ESET’s Internet Security program was the only product without false positives.
Many devices have permanent internet connections. The result of the offline detection test underscores the importance of cloud connectivity and testing for Microsoft’s security product.
