An Extra.DAT is a temporary detection file created by McAfee Labs. It detects and removes threats that have not yet been added to the daily DAT files. This article describes how to manually check in the Extra.DAT update package to the Master Repository, and how to deploy it using ePO 5.x.

IMPORTANT: These instructions are intended for use by ePO administrators. You are responsible for preventing adverse effects as a result of performing these instructions. Before proceeding, it is strongly recommended that you back up the ePO server system, database, and policies. See KB66616 for details about backing up the ePO server.

Check in the Extra.DAT

  • You cannot check in packages while any pull or replication tasks are running.
  • If your environment requires testing new packages before deploying them, it is recommended to use the Evaluation branch. After you finish testing the packages, move them to the Current branch on the Software, Master Repository tab. 
  1. Log on to the ePO console. To open a remote console through Internet Explorer, type one of the following URLs in your browser:

  2. Click Menu, Software, Master Repository.
  3. Click Actions and select Check In Package.
  4. Select Extra.DAT.
  5. Click Browse, locate the Extra.DAT, and then click Open.
  6. Click Next. Information is displayed about the Extra.DAT you are about to add to the repository.
  7. Click Next.
  8. Select the branch where you want to add the Extra.DAT. The default branch is Current.
  9. Click Save. The Extra.DAT is now listed under Packages in the Master Repository list on the Master Repository page.
  10. If you have distributed repositories, run a Repository Replication task to distribute the Extra.DAT to all Distributed or Remote repositories.

Deploy the Extra.DAT
  1. Create a new McAfee Agent Product Update task to deploy the Extra.DAT, and schedule it to Run Immediately.
  2. Perform an agent wake-up call to send the new Update task to your clients and apply the Extra.DAT.

    NOTE: If you prefer, you can reschedule an existing Update task to deploy the Extra.DAT.
