AV-Comparatives 发现 Microsoft Defender 具有最差的离线检测率之一

Anti-malware assessment company AV-Comparatives today released its latest March 2022 report. The report found that Microsoft's in-house Defender antivirus software had one of the worst offline detection rates, at just 60.3 percent. Meanwhile, G DATA topped the list with 98.6%. This means Microsoft Defender relies heavily on cloud-based protection.

However, Microsoft products have the best online detection and protection rates. If you're wondering what the difference between protection and detection is, here's how AV-Comparatives defines the two:

The file detection tests we performed in previous years were detection-only tests. That is, it only tests the security program's ability to detect malicious program files before execution.

[..] This malware protection test not only checks detection rate, but also protection capabilities, which is the ability to prevent a malicious program from actually making any changes to the system.

You can find a complete comparison of offline and online detection rates and protection rates for various anti-malware solutions in the image below:

In addition to the malware protection tests, AV-Comparatives also publishes data from what it calls real-world protection tests, which you can see in the image below. Here's how the company differentiates between the two:

In the malware protection test, malicious files are executed on the system. In a real-world protection test, the vector is the network, while in a malware protection test, the vector can be a network drive, a USB, or a scenario where the overlay malware is already on the disk.
