The scanner update settings are, by default, set to begin updating your engines five minutes after the FSCController is started. For more information about configuring scanning options, see Transport Scan Job, Realtime Scan Job, and Manual Scan Job.If you are using a proxy server to access the Internet for scanner updates, these scheduled updates will fail.After Forefront Security for Exchange Server has automatically downloaded an updated scan engine, it automatically puts that engine to use.During file scanner updates, only the engine being updated is taken offline. When scheduling engine updates on multiple servers in your organization, it is recommended that you stagger the updates by at least five minutes, to prevent servers from timing out during the update process.Forefront Security for Exchange Server enables you to choose virus scanning engines from multiple vendors.The standard Forefront Security for Exchange Server license includes all currently integrated antivirus engines.For information about configuring Forefront Security for Exchange Server to use a proxy server to retrieve updates, see Updating the file scanners through a proxy.After the configuration settings have been entered, use the Update Now button on the Scanner Updates work pane to perform an immediate scanner update for each engine.

Example: Server Ex1 receives its updates automatically from the Microsoft HTTP server.
Ex1 has Forefront Security for Exchange Server installed in C:\Program Files(x86)\Microsoft Forefront Security\Exchange Server, and you have created a share, called Admin Share, that begins at the Engines directory.
Scan engines, signature files, and worm list updates can be downloaded automatically from the Microsoft HTTP server, or from another Exchange server running Forefront Security for Exchange Server.
Setting a schedule for checking the HTTP or Exchange server for a new scan engine means that you are automatically protected against new viruses without having to check versions or manually update the files.
FSE will also download the full update package rather than perform an incremental update.
