This policy setting manages the behavior for notifying registered antivirus programs. If multiple programs are registered, they will all be notified.

The recommended state for this setting is: Enabled.

Note: An updated antivirus program must be installed for this policy setting to function properly.


Antivirus programs that do not perform on-access checks may not be able to scan downloaded files.


To establish the recommended configuration via GP, set the following UI path to Enabled:

User Configuration\Policies\Administrative Templates\Windows Components\Attachment Manager\Notify antivirus programs when opening attachments

Note: This Group Policy path is provided by the Group Policy template AttachmentManager.admx/adml that is included with all versions of the Microsoft Windows Administrative Templates.


Windows tells the registered antivirus program(s) to scan the file when a user opens a file attachment. If the antivirus program fails, the attachment is blocked from being opened.

Default Value:

Disabled. (Windows does not call the registered antivirus program(s) when file attachments are opened.)
