McAfee Internet Security 5.0

As it installs itself, VirusScan software will examine your computer’s memory 
and your hard disk’s boot sectors to verify that it can safely copy its files to 
your hard disk without risking their infection. During that installation, Setup 
offers to create an Emergency Disk you can use to start your system in a 
virus-free environment. Should the VirusScan software itself become infected, 
or if you want to be sure your computer is clean before you install any other 
software, create and use an Emergency Disk to start your computer.

VirusScan software comes with an Emergency Disk wizard that makes disk 
creation simple and fast.

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 
specialized set of virus definition (.DAT) files that focus on ferreting out 
boot-sector viruses. If you have already installed VirusScan software with 
default Setup options, you’ll find these .DAT files in this location on your hard 
disk:

The special .DAT files have these names:

M

EMCLEAN.DAT

M

EMNAMES.DAT

M

EMSCAN.DAT

McAfee periodically updates these .DAT files to detect new boot-sector 
viruses. You can download updated Emergency .DAT files from this location:

McAfee recommends that you download new Emergency .DAT files directly 
to a newly formatted floppy disk in order to reduce the risk of infection.
