Thank you for purchasing McAfee« VirusScanÖ software, a powerful and advanced system designed to detect, eradicate, and prevent computer viruses. VirusScan will help you protect one of your most important assetsù
the information on your personal computer or local area network.
VirusScan includes two main programs:
1 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:
1 A graphical interface so that you can select commands and options using a mouse and keyboard, if you like.
1 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.
1 The VShieldÖ 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 com-puters (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.
How to use this manual
This manual will help you get VirusScan running quickly and properly on DOS, Windows, and OS/2 systems.
1 All the key information is in Chapter 2, "Don't skip this chapter." Please don't install VirusScan before reading it, even if you are a PC power user or already familiar with Scan. Installing and using VirusScan is not like using other software.
The rest of Chapter 1, "Welcome to VirusScan," describes the programs and files on your VirusScan disk, system requirements, how to register, and how to get help.
Chapter 3, "Using interactive Scan," describes how to use the graphical version of Scan in Windows, DOS, and OS/2, including scanning your system, cleaning your system, and selecting scanning options.
Chapter 4, "VirusScan reference," and Chapter 5, "VShield reference," contain reference information for Scan and VShield, respectively. Many users will not need to read these chapters, because basic operation of VirusScan, as described in Chapter 2, will detect and remove most viruses from your system. The options described in Chapters\x114 and 5 offer additional power and control, and are most useful in vulnerable environments and to network administrators and information services staff.
Chapter 6, "Tips & troubleshooting," explains how to get the most out of -VirusScan, and how to cope with some common problems.
Appendix A describes how to retrieve new versions of McAfee programs using your communications software.
Appendix B describes differences in command line options between VirusScan version 1.5 and version 2.0.

What VirusScan includes
In addition to Scan and VShield, your VirusScan diskette contains another program that will help you use VirusScan. The Validate program ensures that new versions of VirusScan software you've obtained are authentic and unmodified.
Your VirusScan diskette also contains several useful text files, which you can view and print with a text editor, word processor, or print command. You'll find version-specific information in the README.1ST file.
VirusScan files after installation
The VirusScan installation software puts the appropriate program files on your hard disk for the version you have purchased (DOS, Windows, or OS/2). It also installs several useful text files.
AGENTS.TXT\x14lists McAfee authorized agents.
AUTOEXEC.VSH\x14is a sample AUTOEXEC.BAT file showing how to use VShield.
COMPUSER.TXT\x14explains how to use the McAfee Virus Help Forum on -CompuServe and how to get a free introductory membership.
PACKING.LST\x14lists the names of all the files included in the VirusScan package.
README.1ST\x14includes the validation information for all the program files installed, as well as any new instructions.
System requirements
The VirusScan programs require an IBM-compatible personal computer and any of the following operating systems:
1 DOS 3.1 or later and at least 340Kb of free RAM for the command line -programs and 530Kb of free RAM for the graphical programs.
1 Windows 3.1 or later and at least 4Mb of RAM.
1 IBM OS/2 2.1 or later and at least 8Mb of RAM.
VShield is a terminate-and-stay-resident (TSR) program that requires 67Kb of free memory. VShield attempts to minimize the use of conventional memory by loading into expanded, extended, or upper memory. For more information, see "VShield reference" in Chapter 5.
