Information about the new antivirus engine for Forefront and Antigen products

  • Article

Microsoft is upgrading the multi-engine protection in all Forefront server security products to support a newer version of the antivirus engine. The newer version will provide customers with improved scanning times and reduced signature file size. The new engine replaces the older engine.

This new engine publishes update files in a subdirectory – the first engine in the Forefront engine mix to do so. In order to accommodate this new publishing model, Microsoft is releasing a series of roll-ups that will:

• Include the new antivirus engine

• Ensure that any engine that publishes update files in a subdirectory will update correctly

Customers must install the rollups by Jan. 31, 2011.
