The WHATSNEW.TXT files that accompany each product will no
longer list the viruses the product detects and removes.
That information will appear only in the WHATSNEW.TXT file
that comes with the .DAT update.

____________
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

szInstallDir
szProductVer
szSerialNum
szUpdateEXE

____________
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.

__________________________
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.
