Product Highlights

McAfee's BootShield protects against virus infections in your system's boot
sector. Here are the product's main features:

- Secure installation--since the key to protecting against boot sector
  viruses is to start with a virus-free boot sector, the Scan component of
  BootShield is automatically run during installation to determine whether
  boot viruses exist before installing BootShield.

- Ability to identify and prevent infection by boot sector viruses--once
  intalled, the BootLock component "locks out" viruses from the computer's
  boot sector.

- Optional image backup utility -- ImageStor is BootShield's disaster
  recovery utility. It's easy to use and allows you to quickly create a
  backup disk image which you can use to restore data in the event of a data
  loss situation.

What is New in this Release

  *  Enhanced installation program.

     The new installation script now detects what operating systems are
     installed on the destination computer.  If Windows 95, Windows NT, or
     OS/2 is installed, the script will warn the user about possible problems
     they might encounter.

     The script also detects if the user is currently running Windows or OS/2
     and aborts the installation.  This is because the nature of these
     environments prevent the proper activation of the BootLock technology.


  *  Expanded error messages.

     Several of the error message within the BootLock portion of the program
     were expanded to provide clearer information about the nature of the
     problem and the steps to resolve it.


  *  Updated virus definitions for SCAN component.

     The SCAN component (from the VirusScan product) relies upon external
     data files for ensuring that the system is free from boot viruses prior
     to installation.  These data files have been updated to increase the
     number of viruses which can be identified.  This helps ensure that
     the computer is clean before the BootLock protection is enabled.


_____________________________________________
What to do if You Received the Product Online

BootShield is available from the McAfee online services (for example, our
BBS and Web site -- see the contact information below).  You'll receive
these files:

BSH-101E.ZIP       BootShield 1.01 (Evaluation)
BSH-101L.ZIP       BootShield 1.01 (Licensed)
BSH10MAN.ZIP       Manual for BootShield 1.0


Decompressing Your Files:

Use PKUNZIP to decompress the BootShield product files either onto floppy
diskettes or into a directory on your hard drive or server.  Before you
install, you'll want to verify that the files you downloaded are exactly the
same as when we posted them online.  We recommend you perform this task for
maximum anti-virus protection.  You can use the Validate program included
with this package to accomplish this.  For information on using Validate,
consult the README.1ST file.

Before You Install

Before you install, we recommend that you access the online user's manual
which contains detailed installation instructions.  To do this, follow the
steps below:

   *  Start the Acrobat Reader.

      NOTE: If you do not already have the Acrobat Reader, you can download
      it from the McAfee home page located at www.mcafee.com.  Once you
      arrive at the home page, just select 'Download McAfee',
      'Download McAfee Product,' and get the file ACROWIN.ZIP from the
      utility area.  Then, unZIP the file and  run ACROREAD.EXE and follow
      the instructions on the screen to install the reader.

   *  Open the BSHIELD.PDF file.

   *  Click on the table of contents topic containing the information you'd
      like to view.  You'll find installation instructions in Chapter 3,
      "Protecting the Boot Sector."


___________________________________________________
Changing from an Evaluation to the Licensed Version

To begin using the licensed version of BootShield, you need to uninstall
your evaluation copy.  To uninstall, you'll need to have the backup diskette
that was created during installation for the specific machine.  Without the
backup diskette, you cannot remove BootLock from the system.  See the online
manual for step-by-step instructions for uninstalling BootLock.


_______________________
Installation Procedures

Review these basic requirements for installing and running BootShield.

- PC with a 386SX processor or better
- DOS version as follows:
     For BootLock and Scan you need DOS version 3.3 or later
     For ImageStor you need DOS version 6.0 or later
- At least 512 kilobytes of Random Access Memory (RAM)
- At least 2 megabytes of disk space
- For tape backup, a SCSI tape device that use ASPI.


If you're installing from diskette, insert Disk 1.  Or if you downloaded the
product from a McAfee online service, change to the location where the files
were stored after you decompressed them.

Enter the following command at the DOS prompt:

     X:INSTALL X:

where X is the drive that contains the diskette.

Then follow the instructions on the installation screens.  Don't forget to
register your product.  A registration form is provided in the file
README.1ST.

***Note that it is critical to keep the recovery diskette that is created
   during installation on hand.  You may need this diskette should you need
   to remove BootLock from the system -- without it, you may not be able to
   uninstall BootLock.


______________________________________________
Uninstalling BootLock from a Recovery Diskette

When you boot from the BootLock recovery diskette, created by the install
process, and attempt to Uninstall using the BSSETUP.EXE utility, the program
informs you that you need to supply the Workstation ID before you can
complete the process.  However, this will not succeed, even if you specify
the correct information.

In order to remove the BootLock protection while running from the recovery
diskette, you must do the following:
    1.  Execute the BSSETUP.EXE program.
    2.  Choose the Install BootLock option.
    3.  Fill in the Name, Company name, Diskette ID, and Workstation ID
        fields EXACTLY as originally entered during installation.
    4.  Press the <ESC> key - DO NOT choose Start Installation!
    5.  Now, select the Uninstall BootLock or Emergency Uninstallation, as
        needed.

Following these steps, the uninstallation should proceed without any
difficulty.  Note, this problem will not be encountered when running from
the hard drive BootLock is installed to.  Therefore, it is recommended that
you always remove BootLock by running BSSETUP.EXE from the hard drive it is
installed to.  Only if you have difficulty accessing the computer should you
user the Recovery diskette.
