INSTALLATION

* INSTALLING THE PRODUCT *

Perform one of the following installation procedures
depending on which version of VirusScan for DOS you
want to install.

1.  For the installable version of VirusScan for DOS,
    take the following steps:

    a.  Execute the INSTALL.BAT program.
    b.  Follow the on-screen instructions.

    By default, McAfee's installation program makes 
    a directory on the hard disk drive named
    C:\MCAFEE\VIRUSCAN and copies the program files
    to that directory.

    The installation script adds the directory
    to the path statement in your AUTOEXEC.BAT file
    and adds two lines that reference the VShield
    program to provide on-access virus prevention.
    For the most complete virus protection, McAfee
    recommends using the /ANYACCESS switch.

    or  

2.  For the non-installable version of VirusScan for
    DOS, take the following steps:

    a.  Make a directory on your hard disk drive.
    b.  Copy the files to that directory.
    c.  Add that directory to the path statement in
        your AUTOEXEC.BAT file.
                              

* PRIMARY PROGRAM FILES FOR VIRUSSCAN FOR DOS *

Files located in the Install directory:
=======================================

        SCAN.EXE = VirusScan for DOS program
      README.1ST = McAfee information
     PACKING.LST = Packing list
    VALIDATE.EXE = Authenticity validation program
        SCAN.DAT = Virus scan definition data
       NAMES.DAT = Virus names definition data
       CLEAN.DAT = Virus clean definition data
    WHATSNEW.TXT = What's New document
      AGENTS.TXT = McAfee authorized agents


* TESTING YOUR INSTALLATION *

The Eicar Standard AntiVirus Test File is a combined effort 
by anti-virus vendors throughout the world to come up 
with one standard by which customers can verify their 
anti-virus installations.

To test your installation, copy the following line into its
own file and name it EICAR.COM.

X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

When done, you will have a 69- or 70-byte file.

When VirusScan is applied to this file, SCAN will report 
finding the EICAR-STANDARD-AV-TEST-FILE virus.

It is important to know that THIS IS NOT A VIRUS. However,
users often have the need to test that their installations 
function correctly. The anti-virus industry, through the 
European Institute for Computer Antivirus Research, has 
adopted this standard to facilitate this need.

Please delete the file when installation testing is 
completed so unsuspecting users are not unnecessarily 
alarmed.


* UNINSTALLING THE PRODUCT * 

Follow the instructions outlined below to uninstall the
installable version of VirusScan for DOS.
                                         
1.  Execute VSHIELD/REMOVE to remove VShield from
    memory, then remove the files from your hard
    drive and remove any lines in your AUTOEXEC.BAT
    file that call VShield. If an error message is
    displayed indicating that VShield could not be
    removed from memory, take the following step. 
        
2.  Edit your AUTOEXEC.BAT file and remove all lines
    that call VShield, then reboot your system. On
    restarting your system, VShield will not be loaded
    into memory and you can remove the files from your
    hard drive.

    Note: If the files are removed from your hard drive
    prior to removing VShield from memory, an error
    message will be displayed until you remove
    VShield from memory or restart your system.

__________________________
FREQUENTLY ASKED QUESTIONS 

Regularly updated lists of frequently asked questions 
about McAfee products also are available on McAfee's 
BBS, website, and CompuServe and AOL forums.
   
Q:  How do I enable McAfee's Centralized Alerting and
    Reporting option?

A:  VirusScan now supports Centralized Alerting and
    Reporting to a remote NetWare or Windows NT server
    running NetShield for Windows NT v2.5.3 and higher
    or NetShield for NetWare v2.3.3 and higher. To set
    up this option on your VirusScan client, use the
    /ALERTPATH <directory> option, where the <directory>
    is the path to the remote NetWare volume or NT
    directory. From this directory, NetShield can
    broadcast or compile the alerts and reports
    according to its established configuration.

    NOTE: The client must have write access to this
    <directory> location and the directory must contain
    the NetShield-supplied CENTALRT.TXT file.

    To send a complete alerting file identifying the
    system and user, establish the following environment
    variables or add them to the AUTOEXEC.BAT file.

      Set COMPUTERNAME=<name of computer>
      Set USERNAME=<user name>

    The alert file sent to the server is an .alr text
    file. Upon receipt of the alert file, NetShield NT
    or NetShield for NetWare sends an alert message to
    an administrator and/or appropriate personnel.


Q:  What can I do to scan my zip drive when VirusScan is
    unable to access it?

A:  If you are experiencing problems accessing your zip
    drive, go to the VirusScan directory, and type
    SCAN X: /NODDA (where X is the letter of your zip
    drive). Enabling this switch will allow you to access
    and scan your zip drive.


Q:  I have created my own Emergency diskette, how
    can I optimize it's performance?

A:  For optimal performance, create a CONFIG.SYS file on
    the boot diskette and add the following lines:

       [CONFIG.SYS]

       DEVICE=HIMEM.SYS
       DOS=HIGH
    
    Also, add the HIMEM.SYS file from the DOS directory
    to the boot diskette. 

    Note: For detailed instructions on creating an Emergency
    diskette, refer to the instructions outlined in your
    online documentation.

 
Q:  What does McAfee recommend for systems that have
    low conventional memory?

A:  McAfee recommends using ScanPM for low memory environ-
    ments. ScanPM is a command-line scanner with a reduced
    conventional memory footprint, that operates in
    protected mode command-line environments.

    ScanPM is available for a free evaluation and can be
    downloaded from the online services listed below.


Q:  What is the difference between the VShield DOS TSR
    and VirusScan for DOS?

A: #1  VShield installs itself in memory and stays
       resident in order to monitor your system for
       viral activity. If an infected program is
       executed or an infected boot sector is accessed,
       VShield will display a warning that a virus
       is present.

A: #2  VirusScan for DOS is an on-demand scanner that
       allows you to perform a complete or partial
       scan of your computer at any time. VirusScan
       for DOS can run customized scans through a
       large set of command line switches.

 
Q:  How can I run VirusScan for DOS from a Netware login
    script without running out of memory?

A:  If you are having memory problems when trying to
    run VirusScan for DOS from a NetWare login script,
    take these steps to resolve the issue:

    1.  Rename LOGIN.EXE to LOGIN1.EXE and remove
        any references to VirusScan.
    2.  Create a batch file named LOGIN.BAT.
    3.  On the first line of the batch file, run your
        scan with whatever switches you want to include.
    4.  On the second line of the batch file, run
        LOGIN1.EXE.
 
    By taking these steps, you eliminate the problem
    of having LOGIN.EXE and SCAN.EXE in memory at the
    same time. This allows VirusScan for DOS to run and
    your login script to be processed without problems.


Q:  Can I clean the Master Boot Record (MBR) of a
    Windows NT file system (NTFS) formatted hard drive?

A:  Yes. Take these steps to clean the MBR. Boot the
    Windows NT computer from a virus-free DOS bootable
    (system) diskette. Then run VirusScan for DOS;
    SCAN C: /BOOT /CLEAN. This will clean the NTFS
    Master Boot Sector and allow Windows NT to
    successfully reboot from the hard disk drive.
    However, VirusScan for DOS will not be able to read
    the rest of the NTFS partition.

    After starting Windows NT, execute VirusScan for
    Windows NT to detect and clean Windows NT file
    infections.



Q:  Can I update VirusScan's data files to detect
    new viruses?

A:  Yes. If your data files are dangerously out-of-date,
    VirusScan for DOS will prompt you to update them.
    If you have Internet access, you can download
    updated VirusScan data files from the McAfee Web 
    Site, BBS, or other online resources. To download 
    from the McAfee Web Site, follow these steps:

    1.  Go to the McAfee Web Site (http://www.mcafee.com
        or http://205.227.129.97).

    2.  Click on the Download McAfee button in the upper
        left hand column or frame.

    3.  Click on Update Your DAT Files to update DAT files.

    4.  View the information provided on new DAT files
        and downloading.

    5.  Click on Download this Month's DAT.
   
    6.  Data file updates are stored in a compressed form 
        to reduce transmission time. Unzip the files into
        a temporary directory, then copy the files to the
        appropriate directory, replacing your old files.    

    7.  Before performing any scans, shut down your
        computer, wait a few seconds, and turn it on again.
