Deploying An Extra.dat File - McAfee VIRUSSCAN 4.5 Administrator's Manual

Updating and Upgrading VirusScan Software
When you have placed the PKGDESC.INI file, the SETUP.EXE file, and any
SETUP.ISS file you want to use on a central server, configure the AutoUpgrade
utility copies on your workstation computers to download new files from the
share you created on that central server. The AutoUpgrade utilities will
download and install the new files from this package.
To learn more about how the SuperDAT utility works, download the
SuperDAT User's Guide from the McAfee website at:

Otherwise, consult the README.TXT file that comes with each weekly
SuperDAT release.

Deploying an EXTRA.DAT file

The McAfee AVERT research organization will sometimes provide
EXTRA.DAT files to combat high-risk viruses between regular .DAT and
SuperDAT releases. In ordinary circumstances, McAfee researchers publish
these files when they determine that these situations warrant one:
• A virus presents a "medium on-watch" or "high" risk threat of infection.
To learn about what constitutes a medium on-watch or high risk, or about
McAfee AVERT risk assessment in general, visit the AVERT website at:
• A high-prevalence virus threatens an outbreak situation
Ë
When AVERT does publish an EXTRA.DAT file, it will announce its
availability—and a location where you can download the file—when it
publishes a virus alert for a medium on-watch or high-risk virus. If you
subscribe to the Enterprise SecureCast update service, you can receive all such
alert messages if you wish. To learn more, see
SecureCast Service to Get New Data Files."
Once you download an EXTRA.DAT file, you need only copy the file to a
particular directory to have VirusScan software use it immediately. Each time
you start a scan session or a VirusScan application scan operation, the software
checks to see if you have an EXTRA.DAT file located in the correct directory.
If such a file exists, the software will add the EXTRA.DAT virus definitions to
those in its other .DAT files automatically.

IMPORTANT: AVERT does not guarantee that it will make
EXTRA.DAT files available in all such situations. AVERT researchers
reserve the right to assess each situation and determine an appropriate
course of action.
