McAfee Anti-Virus Scanning Engine 6.x.xx
McAfee Security for Microsoft Exchange (MSME) 8.0

Microsoft Exchange
Microsoft Windows


This article describes how to configure MSME 8.0 so that it does not automatically update to the latest Anti-Virus Scanning Engine.
This action is needed in some scenarios where you cannot update all servers to the most current McAfee Scanning Engine without first completing internal testing or limited deployment.


Use the XDATs
To avoid installing the latest Anti-Virus Scanning Engine and keep up to date with the latest DAT Files, disable all update tasks, including those tasks from ePolicy Orchestrator (ePO) or other management solutions.
After you have disabled all update tasks, download and run the McAfee SuperDAT Executables (XDATs) that only contain DAT File updates and not engine updates. XDATs are updated daily and are available from the DATs section at: https://www.mcafee.com/enterprise/en-us/downloads/security-updates.html.


If you have installed MSME on a server with no other McAfee products, you can avoid updating the Engine. Do so by importing an AutoUpdate Repository List (Sitelist.xml) that points to any repositories that do not have the latest Engine available for download. See Related Information below for information about the configuration of ePO repositories for this scenario.

NOTE: If the Sitelist.xml contains the site NAIHTTP, and if this site is accessed, there is no way to avoid updating the Engine.
If you have installed MSME with an ePO Agent, see the Related Information section for details about configuring the Repositories and Agent Update Tasks.

If you have installed MSME on a server with only VirusScan Enterprise (VSE) 8.xx, you can configure VSE not to update the Engine:
  1. Open the VSE 8.xx console.
  2. Right-click on all Autoupdate tasks.
  3. Select Properties.
  4. Deselect Get newer detection Engine and DATs if available.
  5. Click Apply, and then click OK.
