NEW FEATURES 

1.  VirusScan detects and cleans files infected with the
    W97M/MELISSA virus and its variants. For up-to-date
    detection and removal capability, visit the Network
    Associates A.V.E.R.T. website at www.avertlabs.com.

2.  A new Network Associates scanning engine is at the heart
    of VirusScan v4.0.3. Created and backed by the combined
    efforts of the McAfee Labs and Dr Solomon anti-virus
    research teams, this engine delivers outstanding virus
    detection and cleaning rates. The new engine also
    detects viruses in nearly all of the popular compressed
    file formats.

3.  A new Emergency Disk wizard now guides you through the
    process of formatting a floppy disk, copying necessary
    files to it, and preparing the disk for use. To make
    your Emergency Disk bootable, be sure to select the
    Copy System Files checkbox in the Format dialog box
    when it appears. The Emergency Disk you create is now
    easier to use and more powerful than in previous
    VirusScan versions.

    When you run a scan operation from the Emergency Disk
    you create, you can choose the .DAT files to use for
    that operation from a simple menu arrangement. Choosing
    the .DAT files installed on your hard disk allows you
    to run more powerful scan operations.

4.  A new VShield Properties dialog box groups the 
    configuration options for VShield's long-standing
    System Scan module with those for a new, optional
    set of modules: E-mail Scan, Internet Filter, and
    Download Scan. For even quicker and easier setup,
    VShield includes a configuration wizard that enables
    the most common scanning options for an excellent
    balance between system performance and virus
    protection. Now you can set up VShield in one quick
    pass and get complete protection from viruses and
    malicious software at all potential points of entry.
    To activate these optional features, you must install
    VirusScan using the Custom Setup option.

5.  Download Scan also examines other files you choose to
    download, while the Internet Filter module detects
    hostile Java applets and ActiveX controls. You can also
    configure Internet Filter to block access to specific
    undesirable sites. With this broad focus, VirusScan
    seals all points of entry for viruses and other
    malicious software.

6.  New versions of VirusScan Command Line components give
    VirusScan for Windows 95 and Windows 98 powerful and
    up-to-date protection for command-line environments.

7.  VShield will start looking for viruses in new mail that
    you receive in your MAPI mailbox while you are logged
    in to your MAPI mail server. In this way, VShield
    provides you with continuous, real-time anti-virus
    protection for your MAPI-based e-mail, whichever profile
    you use. You can set VShield to clean any viruses it
    finds in your e-mail, or have VShield delete or move the
    infected files to a quarantine folder.

8.  VirusScan's heuristic scanning technology evaluates the
    probability that a file or a macro might be infected by
    a new, unidentified virus. You can choose to use
    heuristic scanning to look for file-infecting viruses,
    macro viruses, or both.

9.  A revamped VShield Security module allows you to protect
    individual property pages for any VShield module against
    unauthorized changes. Use it to keep others who use your
    computer from making changes, or configure VShield with
    those settings you want all users on your network to
    have, then distribute password-protected settings files
    to enforce a network-wide anti-virus security policy.

10. A rewritten VirusScan Scheduler replaces the AV Console
    component included with previous VirusScan versions. It
    now includes right-click functionality that allows you
    to create new tasks and view activity logs directly
    from the task list. An enhanced scheduling function
    allows you to run your tasks at a random interval within
    60 minutes of the time you set for them. This feature
    allows you to avoid clogging network bandwidth with
    simultaneous update or upgrade requests, or cross-
    network scanning tasks.

____________
KNOWN ISSUES

1.  Using DOS memory managers might cause VirusScan to
    falsely detect viruses in memory. Since Windows 95 and
    Windows 98 no longer require DOS memory managers, you
    can eliminate false warnings by preceding each line in
    your CONFIG.SYS file that includes settings for a DOS
    memory manager with REM. This deactivates the memory
    manager. To learn more about working with your
    CONFIG.SYS file, see your DOS or Windows documentation.

2.  If you use a password to protect your VShield
    configuration options, VShield will ask you for that
    password whenever you open the VShield Properties
    dialog box. Use your mouse to click inside the text
    box provided in order to enter the password--keyboard
    shortcuts will not work. Microsoft acknowledges this
    issue in its Knowledge Base Article ID #Q84133. Next,
    click OK to use the password you enter. To close the
    password verification dialog box without entering a
    password, click Cancel.

3.  Disk defragmentation programs move files as they work
    to maximize hard disk efficiency. If you have VShield,
    VirusScan, or other applications active during a disk
    defragmentation operation, your disk defragmentation
    program might tell you that it cannot find the active
    application files. This is normal and does not mean
    that the files do not exist. To avoid error messages
    like this, close all open applications and disable
    VShield, then run your disk defragmentation operation
    again. 

4.  VShield will not detect infected files within a .zip
    archive if you have Novell's Client32 installed on
    your computer, and you:

    * Use Universal Naming Convention (UNC) notation to
      navigate to a directory on a NetWare server that
      contains the infected archive; and
    * Extract the infected files from the archive into
      the same directory.

    To avoid this problem, map a drive letter on your
    computer to the target directory on the NetWare
    server before you extract the compressed files. To
    ensure maximum anti-virus protection for your NetWare
    servers, install and use NetShield NetWare from
    Network Associates.

5.  If you ask VShield to prompt you for an action when
    it finds a virus or a hostile object and you choose
    to have VShield move the infected file to a quarantine
    directory, VShield does not retain the correct
    filename for the infected file. Instead, VShield
    renames the infected file as it moves it. As a result,
    the infected file appears on the hard disk with a
    completely different filename and a .TMP extension.

    If you tell VShield to move infected files to a
    quarantine directory automatically, however, the
    program will retain the correct file names.

6.  If you start your computer with a VirusScan Emergency
    Disk that you created, the Emergency Disk utility will
    quit to a command prompt when it detects and cleans a
    boot sector infection. To ensure that you have removed
    all infecting viruses from your system, Network
    Associates recommends that you use the Emergency Disk
    to restart your computer again, then run another scan
    operation, before you restart your computer normally.

7.  VirusScan will detect and remove the XF/SIC.A virus
    from infected Microsoft Excel documents. If you later
    use Excel 97 to open a file from which VirusScan has
    removed this virus, Excel will tell you that it cannot
    find a particular worksheet within the file at a
    particular cell reference. It will also tell you that
    continuing could damage your worksheet and ask you
    whether you want to cancel your request to open
    the file. The worksheet name it mentions will vary.

    You may safely open the worksheet. Click No in the
    confirmation dialog box to continue.

    To prevent the message from reappearing, open the
    document in Excel, then click the Insert menu, point
    to Name, then choose Define. In the dialog box that
    appears, delete the entries Auto_Open and Auto_Close.
    Save and close the file normally.

8.  VirusScan's Internet Filter module does not block any
    IP addresses you have asked it to block if you connect
    to the Internet through America Online.

9.  If you use software that blocks online advertisements,
    such as Ads-Off, while you have VShield active, your
    system could become unstable.

10. VShield will not detect infected files contained in a
    .ZIP archive if:

    * You use a WinZip plug-in for Netscape Navigator;
    * You specify a particular directory into which you
      want the WinZip plug in to extract the infected
      files; and

11. VirusScan will not detect more than one infected file or
    object embedded within Microsoft Office files.

12. VirusScan does not include support for right-click scan
    operations on the My Documents folder in Windows 98.

13. If you install this version of VirusScan on a system
    that already has NetShield's AntiVirus Console installed
    on it, then later remove VirusScan from that system,
    you'll see an error message that tells you VirusScan
    cannot find a certain registry key. This error also
    occurs if you install VirusScan first, then install
    the AntiVirus Console, then remove VirusScan.
    
    Both NetShield and VirusScan share particular registry
    keys, but each program gives these keys different values.
    To avoid this error, you can reinstall the AntiVirus
    Console. Alternatively, you can back up your registry
    file, install the AntiVirus Console, then restore your
    registry file in order to preserve the correct settings.

    The affected registry keys are:

    HKLM\Software\McAfee\VirusScan
          ConsoleEXE
          szVSTempDir
          dwDefaultServerPlatform
          dwCommTimeOut
          Product
          szInstallDir
          szProductVer
          szSerialNum
          szUpdateEXE
          szVirusInfoURLValue
          szVirDefVer
          szVirDefDate
          szEngineVer

____________
INSTALLATION         

* INSTALLING VIRUSSCAN *

1.  Insert the floppy disk or compact disc with your copy
    of VirusScan into your floppy disk drive or CD-ROM
    drive.

    If you downloaded a compressed copy of VirusScan
    from the Network Associates website or other electronic
    service, create a temporary directory on your hard disk
    or on a disk available on your network, then extract
    the files you downloaded into that directory.

2.  Click Start in the Windows taskbar, then choose Run.

3.  Type x:\setup.exe in the Run dialog box to start the
    installation utility from a floppy disk. To start the
    utility from a CD-ROM, type x:\win95\setup.exe. In both
    cases, x is the drive letter that designates your
    floppy drive or your CD-ROM drive.

    If you extracted files that you downloaded to your
    hard disk or to a disk on your network, specify the
    path to the correct directory. For example, type
    C:\DOWNLOAD\SETUP.EXE.

4.  Click OK to continue.

    The VirusScan installation wizard will start. Follow
    the instructions shown on each wizard pane to choose
    the VirusScan options you want.

    NOTE: The installation procedure outlined in the 
    VirusScan User's Guide has changed. To install the
    VShield modules responsible for scanning your POP or
    SMTP Internet mail, for scanning your corporate
    cc:Mail system, or for filtering harmful ActiveX or
    Java objects and dangerous Internet sites, you must
    choose the Custom Installation option and select
    each of these components.
    
    The Typical or Compact installation will, however,
    install the VShield component responsible for scanning
    your MAPI-based email systems.

5.  When you finish your installation, restart your
    computer.

* TESTING YOUR INSTALLATION *
                         
The Eicar Standard AntiVirus Test File is a combined
effort by anti-virus vendors throughout the world to
implement one standard by which customers can verify
their anti-virus installations.

To test your installation, copy the following line
into its own file, then save the file with the name
EICAR.COM.

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

The file size will be 69 or 70 bytes.

Next, start your anti-virus software and allow it to scan
the directory that contains EICAR.COM. When your software
scans this file, it will report finding the
EICAR virus.

Note that this file is NOT A VIRUS. Delete the file
when you have finished testing your installation to
avoid alarming unsuspecting users.

UNINSTALLING VIRUSSCAN

To uninstall VirusScan, click Start in the Windows taskbar,
choose Settings, point to Control Panel, and open. Open the
Add/Remove Programs utility from the folder. Highlight
VirusScan on the program list, and click Add/Remove to
uninstall VirusScan.

To remove VirusScan without using the uninstall utility,
follow these steps: 

1.  Remove references to VirusScan from your AUTOEXEC.BAT
    and your SYSTEM.INI files. To do so, follow these
    steps:

    A.  Start the Windows system editor. Click Start in the
        Windows taskbar, then choose Run. Type SYSEDIT in
        the Run dialog box, then click OK.
    
        A set of text files will open on your screen. Your
        AUTOEXEC.BAT file should appear as the first or
        topmost window in this set. Click the title bar for
        the SYSTEM.INI window to bring it to the foreground,
        then locate this line:

        [boot]SCRNSAVE.EXE=C:\PROGRA~1\NETWOR~1\MCAFEE~1\SCRSCAN.EXE

    B.  Change the line to read:

        [boot]SCRNSAVE.EXE=C:\WINDOWS\SYSTEM\WINDOW~1.SCR    

    D.  When you have restored your SYSTEM.INI file to its
        original state, choose Save from the SYSEDIT File
        menu to save your changes, then choose Exit from the
        File menu to quit the SYSEDIT application.

2.  Remove VirusScan icons from the Start menu. To do this,
    follow these steps:

    A.  Click Start in the Windows taskbar, point to
        Settings, then choose Taskbar.

    B.  Click the Start Menu Programs tab.

    C.  Click the Remove button.

    D.  Select the McAfee VirusScan folder in the list that
        appears in the Remove Shortcuts/Folders dialog box,
        then click Remove.

    E.  Windows will ask you to confirm your action. Click
        Yes to continue.

    F.  Click Close to close the Remove Shortcuts/Folders
        dialog box, then click OK to close the Taskbar
        Properties dialog box.

3.  Edit the Registry. To do this, follow these steps:

    A.  Start the Windows Registry editor. Click Start in
        the Windows taskbar, then choose Run. Type REGEDIT
        in the Run dialog box, then click OK.

    B.  Click + to expand the HKEY_LOCAL_MACHINE folder,
        click + again to expand the SOFTWARE folder, then
        click one more time to expand the CLASSES folder.
        Next, delete these keys or entries: 

        \.vsc

FREQUENTLY ASKED QUESTIONS 

Regularly updated lists of frequently asked questions 
about Network Associates products are also available on
the Network Associates website, on CompuServe, and on
America Online.

Q:  I use both cc:Mail and a MAPI-compliant e-mail system
    at work. Can I have VShield scan both of these systems
    at once or switch back and forth between them?

A:  VShield's E-Mail Scan module includes support for only
    one e-mail client at any given time. You may not, for
    example, have the E-Mail Scan module scan both a
    MAPI-compliant mailbox and a Lotus cc:Mail server at
    the same time. You can, however, scan first one mailbox
    then switch the E-Mail Scan module so that it scans the
    other mailbox. You can also have VShield's E-Mail Scan
    module examine your cc:Mail mailbox in the background,
    then have VirusScan's E-Mail Scan on-demand component
    begin scanning your MAPI mailbox.


Q:  I am installing new software on my computer, and the
    manual recommends disabling any anti-virus software.
    How do I disable VShield without uninstalling it?

A:  Right-click the VShield icon located in your system
    tray next to the system clock, point to Enable, then
    choose System Scan from the shortcut menu. If System
    Scan does not have a checkmark beside it in this menu,
    it is already disabled. After you install your new
    software, reactivate VShield by right-clicking the
    VShield icon in the system tray, pointing to Enable,
    then choosing System Scan from the shortcut menu. If
    System Scan has a checkmark next to it in the menu,
    it is enabled. 


Q:  I've activated VirusScan's heuristic scanning option,
    and now it identifies some viruses as "unknown." Why?

A:  VirusScan's heuristic scanning feature looks for certain
    "virus-like" characteristics in the files it scans. When
    it finds a sufficient number of these characteristics,
    VirusScan concludes that the file is infected. This
    powerful scanning technique allows VirusScan to discover
    viruses that are so new that they do not yet have names
    or identities. VirusScan will, however, identify viruses
    by name when they match its list of known viruses. 


Q:  When I choose Virus List in VirusScan, I get a message
    that tells me it's unable to connect. What's happening?

A:  Network Associates now stores its virus information in
    a web-based Virus Information Library. To use this
    feature, you must have a network-based or dial-up
    Internet connection and web browsing software installed
    on your computer. If you still cannot connect, start
    your web browser and enter this address into the text
    box at the top of your browser window:
  
    http://vil.mcafee.com/villib/alpha.asp


Q:  I have an existing VirusScan installation with a lot
    of custom settings. Can I keep these settings when I
    upgrade to the current VirusScan version?


A:  The Setup utility for VirusScan v4.0.3 or later will
    offer to preserve your settings from previous versions
    during installation. This feature will preserve any
    configuration options you set in v3.2.0 or later. It
    will make every attempt to preserve settings for
    VirusScan 3.x versions earlier than v3.2.0, but
    Network Associates does not support this feature for
    versions earlier than v3.2.0. Setup will NOT preserve
    settings from VirusScan v2.x, nor from any version of
    WebScanX.


Q:  How can I get Setup to remove all files, including
    settings files, from existing VirusScan versions when
    I run a silent installation?

A:  To have Setup remove all VirusScan files during a silent
    installation, open the SETUP.ISS file that you use for
    the silent installation, then find the section that
    reads:

    [DLG_12110-0]
    Result=0

    If the value shown for Result is zero, Setup will
    preserve your VirusScan settings. If the value is 1,
    Setup will remove VirusScan completely. Change the
    value to reflect the action you want Setup to take,
    then save and close SETUP.ISS. To learn more about 
    recording and running a silent installation, consult
    the VirusScan User's Guide.


Q:  When VirusScan detects an infection in files compressed
    in .CAB or ZIP-SFX format, why doesn't VirusScan clean,
    delete, or move the files?

A:  Because files compressed in .CAB and ZIP-SFX formats can
    include a Microsoft Authenticode certificate, altering
    the files can render them unusable. To avoid this
    possibility, VirusScan does not clean, delete, or move
    infected files compressed in .CAB or ZIP-SFX format.
    Network Associates recommends that you decompress any
    infected files compressed in these formats, then run
    VirusScan again to clean the uncompressed files.


Q:  VirusScan detected a virus on my system, but it is not
    one of the default files listed in its Program
    Extensions dialog box. Therefore, I suspect it might be
    a false detection. What can I do to verify a detected
    virus?

A:  If you suspect a false detection on a non-executable 
    file, run VirusScan's command line scanner, SCAN.EXE, 
    to verify the infection. If VirusScan detects a virus
    and SCAN.EXE does not, download the latest .DAT file
    update, then scan your system again. If VirusScan still
    detects a virus that you suspect is a false detection,
    please report the issue to Network Associates technical
    support.


Q:  I would like to purchase and download the latest
    version of VirusScan from one of the Network Associates
    electronic services, but I do not want to give my 
    credit card information over the Internet for
    security purposes. Can I purchase VirusScan via modem
    and download the product via the Internet?

A:  Yes. The first time you download VirusScan, the Network
    Associates SecureCast wizard will prompt you to select
    the transmission method you prefer to use to download
    your Network Associates product. It will also prompt
    you to transmit your encrypted credit card information.

    At the Transaction Connection Type dialog box, select
    Internet to download your order via the Internet.
    At the Security Connection Type dialog box, select
    Direct Dial Modem to transmit your credit card
    information via modem.


Q:  I have created my own Emergency Disk without using
    the Emergency Disk creation utility. Is there anything
    I need to do to be sure that it will work properly?

A:  To have your own Emergency Disk start scanning properly,
    you must create a CONFIG.SYS file on the boot diskette,
    then add these lines:

       DEVICE=HIMEM.SYS
       DOS=HIGH
    
    Add the HIMEM.SYS file from the \WINDOWS directory to
    the boot diskette.

    NOTE: For detailed instructions on creating an
    Emergency Disk, refer to the instructions outlined in
    the VirusScan User's Guide, which you'll find on the
    Network Associates website.

    NOTE ALSO: If you copied the files EMNAMES.DAT,
    EMCLEAN.DAT, and EMSCAN.DAT to the Emergency Disk you
    created (as it states in the User's Guide), you must
    rename these files to NAMES.DAT, CLEAN.DAT, and
    SCAN.DAT, respectively, in order for the Emergency Disk
    to function properly.


Q:  What error codes can CHKVXD.EXE return?

A:  Possible CHKVXD.EXE error level codes, along with their
    descriptions, are:

    65535(-1)= VShield not installed

    0 = VShield enabled

    1 = VShield disabled 


Q:  How can I tell that ScreenScan is working?

A:  ScreenScan does not tell you when it scans your system,
    but if you enable the logging option when you configure
    it, VirusScan will record all ScreenScan activity in
    its log file. 

    
Q:  Can I update Network Associates data (.DAT) files to
    detect new viruses?

A:  Yes, you can install and use the Network Associates
    SecureCast client software to receive updated files
    automatically, as soon as they become available. For
    details, consult the VirusScan User's Guide.
    
    If you need additional assistance with downloading, 
    contact Network Associates Download Support. Contact
    information appears later in this file.


Q:  Why are additional extensions added to the Program Files
    Only list?

A:  As the Network Associates Anti-Virus Emergency Response
    Team finds viruses that can infect new file types, it
    adds new extensions to the default extensions list to
    enhance security. For instance, new viruses can infect
    Microsoft Office binder files, so the default extensions
    list now includes the file extension for these binder
    files so that VirusScan will examine them for viruses.


Q:  I thought I could right-click Microsoft Office .DO?,
    .XL?, or .OBD files, then choose Scan for Viruses
    from a shortcut menu in order to start a scan operation.
    I have Microsoft Office installed, but when I try this,
    it doesn't work. Why not?

A:  If you installed Microsoft Office after you installed
    VirusScan, you might need to reinstall VirusScan to
    enable context-sensitive shortcut menus.


Q:  I am having trouble installing Service Pack 2 for
    Microsoft Exchange Client 5.0. Why?

A:  VShield uses files which the upgrade needs to write to.
    In order to successfully install the service pack,
    you must first close VShield by right-clicking the
    VShield icon the Windows system tray, then selecting
    Exit. You will now be able to successfully run the
    service pack upgrade.


Q:  I'm running Microsoft Exchange Client 5.0, and
    VirusScan's On-Demand scan icons aren't showing on my
    taskbar. Why?

A:  If you're using Microsoft Exchange Client 5.0, the two
    Exchange On-Demand scan icons will not appear on the
    Microsoft Exchange toolbar. This is due to a limitation
    in Exchange. Please refer to your Exchange documentation
    for instructions on how to place these icons onto the
    taskbar within Exchange.


Q:  I installed VirusScan v4.0.3 and now I can't scan my
    cc:Mail mailbox, or Internet mail sent via a POP or
    SMTP server. What happened?

A:  Setup no longer installs by default the VShield
    modules responsible for scanning your POP or SMTP
    Internet mail, for scanning your corporate cc:Mail
    system, or for filtering harmful ActiveX or Java
    objects and dangerous Internet sites. To install these
    components, you must choose the Custom Installation
    option during Setup, then select which of these
    components you want to install. This procedure differs
    from that outlined in the VirusScan User's Guide. 
    
    The Typical or Compact installation will, however,
    install the VShield component responsible for scanning
    your MAPI-based email systems.
