Installing VirusScan Software
Using the Emergency Disk Creation utility
If you choose to create an Emergency Disk during installation, Setup will start
the Emergency Disk wizard in the middle of the VirusScan software
installation, then will return to the Setup sequence when it finishes. To learn
how to create an Emergency Disk, begin with
Step 1 on page 50 . You can also
start the Emergency Disk wizard at any point after you install VirusScan
software.
Š
NOTE: Network Associates strongly recommends that you create an
Emergency Disk during installation, but that you do so after VirusScan
software has scanned your system memory for viruses. If VirusScan
software detects a virus on your system, do
not create an Emergency Disk
on the infected computer.
The Emergency Disk you create includes BOOTSCAN.EXE, a specialized,
small-footprint command-line scanner that can scan your hard disk boot
sectors and Master Boot Record (MBR). BOOTSCAN.EXE works with a
specialized set of .DAT files that focus on ferreting out boot-sector viruses. If
you have already installed VirusScan software with default Setup options, you
can find these .DAT files in this location on your hard disk:
C:\Program Files\Common Files\Network Associates\VirusScan Engine\4.0.xx
The special .DAT files have these names:
• EMCLEAN.DAT
• EMNAMES.DAT
• EMSCAN.DAT
McAfee periodically updates these .DAT files to detect new boot-sector
viruses. You can download updated Emergency .DAT files from this location:

Š
NOTE: McAfee recommends that you download new Emergency .DAT
files directly to a newly formatted floppy disk in order to reduce the risk
of infection.
Because the wizard renames the files and prepares them for use when it
creates your floppy disk, you may not simply copy them directly to an
Emergency Disk that you create yourself. Use the creation wizard to prepare
your Emergency Disk.
