Force Runtime AV Scan

This policy setting only applies to subscription versions of Office, such as Microsoft 365 Apps for enterprise, and to subscription versions of Project and Visio.​ This policy setting controls when Office files are scanned at runtime by an installed Anti-Virus software. Note, files will only be scanned if the Anti-Virus software registers as a provider for runtime scanning. If you enable this policy setting, Office applications will submit all files for a runtime scan by Antivirus. If you disable or do not configure this policy setting, Office will selectively submit certain files, for example encrypted files, for a runtime scan by Antivirus.
