Antivirus: Stsadm properties (Office SharePoint Server)

Office 2007

Updated: September 13, 2007

Applies To: Office SharePoint Server 2007

Updated: 2007-09-13

Windows SharePoint Services 3.0 now allows you to help protect your users from uploading or downloading files that contain viruses. When you have installed an antivirus scanner that is compatible with Windows SharePoint Services 3.0, you can enable the antivirus protection feature for your server. When you enable the antivirus protection feature, files are checked for viruses when a user adds a document to a document library or list, or when a user views a document in a document library or list. If a virus is found, the scanner attempts to clean the file. If the file cannot be cleaned, the scanner blocks the file from being added or viewed.

NoteNote:

If a file is uploaded and is later identified as containing a virus, users will not be able to open the file. In this situation, the administrator can still allow users the ability to save the file locally and open it from their computer. For more information, see Avallowdownload.

You must install Microsoft Office SharePoint Server 2007-compatible antivirus software on any server computer running Office SharePoint Server 2007 before you can enable antivirus protection in Office SharePoint Server 2007. If you are in a server farm configuration, antivirus software must be installed on every front-end Web server in the server farm. Consult your antivirus software vendor to find out whether they offer a virus scanner for use with Office SharePoint Server 2007 and for information about installing the virus scanner.

The antivirus properties are part of the setproperty and getproperty operations. The syntax for the setproperty operation is:

stsadm -o setproperty

   -propertyname <property name>

   -propertyvalue <property value>

   [-url] <URL>

The syntax for the getproperty operation is:

stsadm -o getproperty

   -propertyname <property name>

   [-url] <URL>

NoteNote:

You can substitute -pn for -propertyname and -pv for -propertyvalue.
