The video suggests that Windows Defender has been adding more malware signatures, indicating a potential increase in detection rates. However, the test results show that the proactive detection rate remains low.

Q: Why did the system experience slowdowns and crashes during the test?

The video suggests that Windows Defender's poor performance may be related to its engineering, with the protection possibly being too reactive. This could explain the system slowdowns and crashes observed during the test.

Q: What is the significance of malware spreading through network drives?

The video emphasizes that malware can spread between computers in a network, even without direct user interaction. It highlights the importance of implementing good security practices and policies to isolate infected systems in such situations.

Summary & Key Takeaways

• The video focuses on revisiting Windows Defender with its sandbox feature enabled, which is designed to isolate applications and protect against malware attacks.

• The test involves executing a large number of fresh malware samples and analyzing how well Windows Defender detects and handles them.

• Windows Defender fails to prevent significant damage to the system, with ransomware encrypting files and other malware causing system instability.
