archive scanning limits

About this tag
Archive scanning limits in Microsoft Defender control how deeply the antivirus inspects compressed files like ZIP, RAR, or CAB archives during scans. By default, Defender scans inside archives, which can increase CPU usage and slow down system performance, especially when opening or extracting large archives. Adjusting these limits—such as setting a maximum archive size or depth—can reduce the performance impact without disabling real-time protection. This tag covers methods to configure archive scanning limits via PowerShell, Group Policy, or registry edits, along with trade-offs between security and speed. Topics include tuning Defender for gaming, development, or everyday work, and verifying changes to ensure protection remains effective.
