defender offline scan

The defender offline scan tag covers Microsoft Defender Antivirus Offline Scan, a built-in Windows Security feature in Windows 11 and Windows 10 that restarts the PC and scans for malware before the operating system loads. This tool is designed to detect and remove persistent threats that evade normal scans. Discussions emphasize its integration within Windows Security under Virus & threat protection > Scan options, and clarify that it is not a separate antivirus product but a first-party solution for deep cleaning. Users share when to use it, what to expect during the reboot process, and how it fits into a broader security baseline alongside updates and driver maintenance.
