Installing VirusScan Software
48 McAfee VirusScan Anti-Virus Software
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 new 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.
To start the wizard, click Start in the Windows taskbar, point to Programs ,
then to Network Associates . Next, choose Create Emergency Disk . The
Emergency Disk wizard welcome panel will appear ( Figure 2-14 ).
