Overview

This video tests the effectiveness of Windows Defender on Windows 11 against 100 latest ransomware variants. It compares its performance to a previous test with McAfee, where the ransomware was successful. The video also explores Windows Defender's built-in ransomware protection features and briefly introduces a sponsor solution, Threat Locker.

Key takeaways

• Windows Defender vs. Ransomware: The test aimed to see if Windows Defender could effectively block a large number of the latest ransomware.
• Previous Test Comparison: In a prior test with McAfee, ransomware execution was successful, prompting this test with Windows Defender.
• Ransomware Execution: Despite Windows Defender's presence and latest definitions, one ransomware variant (identified as Nebula) successfully encrypted files on the system.
• Windows Defender Performance: Windows Defender blocked 98 out of 100 ransomware attempts, a significant improvement over McAfee in the previous test, but still allowed one successful encryption.
• Ransomware Protection Features: The video highlights Windows Defender's "controlled folder access" feature as a way to protect specific folders from unauthorized access, acknowledging potential compatibility issues with legitimate applications.
• Smart App Control Limitations: A newer feature, "Smart App Control," was discussed but deemed not a foolproof solution against ransomware, as it can be bypassed if the ransomware is signed.
• Sponsor Segment: Threat Locker, a solution using whitelisting and application control, was presented as a more robust defense, preventing the ransomware from executing by default denying unknown applications.
