Updating and Upgrading VirusScan Software

The current VirusScan release can download and install new .DAT and
engine files from a SuperDAT package, on any supported Windows
platform, without requiring you to restart your computer. You can
download and run SuperDAT packages separately to update and update
your software, or you can use the SuperDAT utility in conjunction with the
AutoUpgrade utility to automate updates to a significant degree. To learn
how to combine the two utilities, see

“Using the AutoUpgrade and

SuperDAT utilities together” on page 128

.

In addition to the weekly SuperDAT package that contains both current
.DAT files and a current scan engine, McAfee will make available a
SuperDAT package that consists only of .DAT files. This executable file
minimizes the need for you to closely manage your .DAT file updates. It
takes care of shutting down any active scan operations, services, or other
memory-resident software components that might interfere with your
updates. It then copies the new files to their proper locations and enables
your software to use them immediately.

•

Packaged .DAT file updates

. McAfee also releases weekly .DAT file

stand-alone packages that you can download, extract, and copy to the
program directory for your software. A .DAT package consists of an
archived .ZIP file named DAT-XXXX.ZIP. The XXXX in the file name is a
series number that changes with each .DAT file release. McAfee does not
recommend this method to update your software, but you can do so when
necessary. To learn more about how to use these packages for your
updates, see the README.TXT file that accompanies each weekly package.

•

EXTRA.DAT files

. Regular McAfee virus definition (.DAT) file releases

protect you quite well against new and still-circulating malicious code. But
even weekly .DAT releases can't always protect you against a swift virus
outbreak, especially in the wake of such e-mail borne viruses as
W97M/MELISSA.

McAfee anti-virus software anticipates exactly this situation. It allows you
to take advantage of capabilities built into the McAfee scan engine to
deploy a small, supplemental virus definition file in between .DAT file
releases. This small EXTRA.DAT file holds the absolutely latest available
virus signature data for viruses that McAfee AVERT researchers have
identified as high-risk contaminants.

The file can help to identify several viruses at once, but because AVERT
researchers ordinarily publish an EXTRA.DAT file as soon as they identify
a high-risk virus, the file frequently targets one or two highly prevalent
agents. AVERT researchers then add the virus definitions they included in
any EXTRA.DAT releases to the following week’s regular .DAT file release.
To learn how to deploy the EXTRA.DAT file, see

“Deploying an

EXTRA.DAT file” on page 130
