CHAPTER 1: WELCOME TO VIRUSSCAN
Thank you for purchasing McAfee(R)'s VirusScan(TM)
software, a powerful and advanced system
designed to detect, eradicate, and prevent
computer viruses. VirusScan will help you
protect one of your most important assets--the
information on your personal computer or local
area network.
VirusScan includes two main programs:
o The Scan program detects known viruses in your
computer's memory or on disks. It can also
detect new and unknown viruses. Once viruses
are detected, it can remove them and restore
your system to normal operation. The Scan
program comes in two forms:
o A graphical interface so that you can select
commands and options using a mouse and
keyboard, if you like. For instructions,
see the on-line documentation.
o A command line interface, so you can run the
program and select options by typing from a
command prompt or from batch or script files,
if you prefer.
o The VShield(TM) memory-resident program
continuously monitors and protects your
system from viruses that might be introduced.
The VirusScan programs run on IBM-PC or 100%
compatible personal computers (PCs) that use
DOS, Windows, or OS/2.
VirusScan is an important element of a
comprehensive security program that includes a
variety of safety measures, such as regular
backups, meaningful password protection,
training, and awareness. We urge you to set up
and comply with such a security program in your
organization. For tips on how to do this, see
"Other sources of information" in this chapter.
