quarantined files

Quarantined files are suspicious or malicious items that Windows Security (formerly Windows Defender) isolates to protect your PC. The Protection History section in Windows Security provides a detailed log of detected threats and quarantined files, allowing you to review each detection, restore a file that was mistakenly flagged, or permanently remove a threat. This feature is essential for managing security actions taken by the system, ensuring you can confirm threats were handled properly or recover important files incorrectly quarantined. Understanding how to access and use Protection History helps you maintain control over your system's security while avoiding accidental data loss.
