NEW FEATURES
1. The Dr Solomon's virus scanning engine is at the heart
of VirusScan 4.0.1. Backed by the world's largest
antivirus research organization, it delivers
outstanding virus detection and cleaning rates. The
new engine also detects viruses in nearly all of the
popular compressed file formats.
2. 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. The
Emergency Disk you create is now easier to use and more
powerful than in previous VirusScan versions.
3. A new VShield Properties dialog box groups the
configuration options for VShield's long-standing
System Scan module with those for its new E-mail Scan,
Internet Filter, and Download Scan modules. 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.
4. VShield's E-mail Scan module looks for viruses in
e-mail attachments you receive via your in-house
corporate e-mail system. VShield's Download Scan
module, meanwhile, checks e-mail you receive via
popular Internet mail applications.
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. Specialized scanners help to protect your MAPI-based
and cc:Mail corporate e-mail systems against virus
threats. Use VShield to scan your corporate e-mail
systems in the background, in a continuous sweep for
viruses that infect your e-mail. Supplement VShield's
E-mail Scan protection with VirusScan's new on-demand
E-mail Scan component, which lets you initiate a scan
operation on MAPI-compliant Microsoft Exchange or
Outlook mailboxes.
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.
11. VirusScan detects and cleans files infected with the
Win95/CIH and Win95/Marburg viruses. These viruses
infect Windows 95 and Windows 98 portable executable
(PE) files. A portable executable file is a Windows
resource file that other executable files can share
--examples include dynamic linking library (.DLL)
files.
12. The new scanning engine also includes improved
detection and cleaning capability for the W97M/Class,
W97M/Groov, and XM/COMPAT.A viruses, along with a
new strain of the XF/PAIX virus.
* NEW VIRUSES DETECTED *
**** IMPORTANT NOTE ****
This release of VirusScan for Windows 95 and Windows 98
functions ONLY with the 40xx .DAT file series, beginning
with the 4001 .DAT file included with this program package.
You CANNOT use VirusScan for Windows 95 and Windows 98
with earlier .DAT file versions, nor may you use the .DAT
files included in this release with 2.x or 3.x versions
of VirusScan for Windows 95 and Windows 98.
****
Because the previous VirusScan scanning engine and the
newly incorporated Dr Solomon scanning engine identify
and classify viruses in different ways, this release of
VirusScan for Windows 95 and Windows 98 does not include a
list of viruses detected or cleaned. Future releases will
incorporate this information, once McAfee Labs adopts a
standard virus naming convention.
The INTERNET.DAT component of the .DAT files included with
this release enables VirusScan to detect these 130 hostile

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. If you unzip a virus-infected file into a directory
on a Novell server that you've specified with Universal
Naming Convention (UNC) notation, VShield does not
detect the infection as the file gets created on the
server directory. If you use Windows Explorer to map
the server directory to your computer, however,
VShield will detect the virus as it gets created. 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 VShield detects a virus in a file that you try to
open from within another application, by default it
will prompt you with a range of possible responses.
If you then choose to clean the infected file, the
application will tell you that it cannot open the
file you just cleaned.
To work around this limitation, click OK to close the
error message, then try to open the file again. The
application should open the file successfully on the
second try.
This issue does not occur if you have set VShield to
prompt you for a response when it finds a virus, but
have also selected Continue Access as one of the
possible responses. Rather than a dialog box with
buttons, VShield displays a full-screen alert that
lists your response options.
To learn more about configuring VShield's response
options, see "Using VShield" in the VirusScan
User's Guide.
7. 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.
10. If you have VShield's E-Mail Scan module enabled,
VShield logs on to your MAPI mail server in order to
scan your mailbox for viruses. Ordinarily, VShield
logs on with your default MAPI profile soon after you
start your computer. But if you start your computer
and wait a while before logging on to your network
domain controller, VShield will prompt you to log on
to your MAPI mail server even if you have not yet
logged on to your network, and even if your MAPI
server is not in the domain you usually log in to.
____________

* 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 VirusScan and allow it to scan the
directory that contains EICAR.COM. When VirusScan
scans this file, it will report finding the
EICAR-STANDARD-AV-TEST-FILE virus.
Note that this file is NOT A VIRUS. Delete the file
when you have finished testing your installation to
avoid alarming unsuspecting users.

Regularly updated lists of frequently asked questions
about Network Associates products also are available on
the Network Associates website, and on CompuServe
and 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 includes log-in support for only one e-mail
system at a time. You may not, for example, have
VShield log in to scan your Microsoft Mail or
MAPI-compliant mail server for viruses, then switch it
to scan a Lotus cc:Mail server. You must first allow
VShield to finish logging on to one type of mail server
--either the MAPI server or the cc:Mail server--before
you tell it to log on to the other type of server.
Q: When I try to restart my computer in MS-DOS mode,
Windows shows me an error message that reads "Windows
cannot restart the computer, or start MS-DOS mode with
messaging service running." The only change I made to
the computer was installing VirusScan and enabling
VShield's E-mail Scan module. What happened?
A: Windows cannot restart your computer in MS-DOS mode if
you have VShield running in the background. To unload
VShield from memory, right-click the VShield icon in
the Windows system tray, then choose Exit from the
shortcut menu that appears.
Q: I've tried to get VShield's E-Mail Scan module to scan
my Microsoft Outlook mailbox for viruses, but it doesn't
seem to be scanning my mailbox at all. What's happening?
A: In order for VShield's E-Mail Scan module to look for
viruses in your mailbox on a MAPI e-mail server, it
must log on to your mail system. VShield does so by
using your default MAPI profile, which consists of a
group of settings keyed to a particular user name and
password. If you have logged on to the server with a
profile other than your default profile, VShield will
not be able to scan your mailbox, because it will not
be able to get access to it via your default profile.
If you have not logged on to the server at all, VShield
will ask you for your user name and password so that
it can log on to the server on your behalf.
To see what you have as your default MAPI profile:
1. Click Start in the Windows taskbar, point to
Settings, then choose Control Panel to open the
Control Panel window.
2. Locate and double-click the Mail icon in the Control
Panel window.
This opens a Properties dialog box with your name
or the name of the person currently logged in to
your computer.
3. Click Show Profiles to open another dialog box
that lists all of the profiles you have enabled
on this computer. At the bottom of the dialog box,
you can choose which profile you want to use to
log on to your mail system initially.
4. Make any changes you want to make, then click
Close to close the control panel.
NOTE: Because MAPI initializes only once during a
Windows session, logging on to a MAPI server means
that you will remain logged on until you restart your
computer. Therefore, if you close your e-mail client
and reopen it, or disable the E-Mail Scan module then
reactivate it, the MAPI server will NOT prompt you for
a user name and password.
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: How can I configure VShield so that network users can
enable or disable VShield options temporarily, but keep
them from saving these changes permanently?
A: First set the options you want in the VShield Properties
dialog box, then click OK to save your changes. Next,
open Windows Explorer and locate the DEFAULT.VSH file
in the VirusScan program directory. Right-click the
file, then choose Properties from the shortcut menu
that appears. In the Properties dialog box, select the
Read-only checkbox in the Attributes area. Your users
can then enable or disable any VShield options they
want to, but their copy of VShield will not save those
changes to the DEFAULT.VSH file.
Q: I've activated VirusScan's heuristic scanning option,
but it won't identify the viruses it detects. Why not?
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://www.nai.com/vinfo
Q: I opened VirusScan Scheduler, then I configured,
activated and scheduled a scan task to run, but it
never did. What happened?
A: To run a scheduled scan task, you must leave VirusScan
Scheduler running. If you close the Scheduler or shut
down your computer, the scheduled task will not run. If
the task misses the time it's supposed to run, it will
not run when you next start your computer or when you
next start the Scheduler, it will wait until the next
scheduled time you have set for it to run.
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 v4.0.1 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: 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: When my screen saver starts, I suddenly see a lot
of activity on my hard disk. What's happening? How do
I stop this activity?
A: VirusScan includes a component called ScreenScan that
scans for viruses on your hard disk during periods
when your computer is idle. In order to use ScreenScan,
you must install it separately as part of a custom
installation. Then, during idle periods, ScreenScan
starts the screen saver you chose in your Windows
preferences property page and begins scanning for
viruses.
You can disable ScreenScan by following these steps:
1. Move your cursor to the Windows 95/98 desktop, then
click your right mouse button.
2. Choose Properties from the shortcut menu that
appears.
3. Click the ScreenScan tab in the Display Properties
dialog box.
4. Clear the Enable Scanning While in Screen Saver Mode
check box.
5. Click OK to close the Display Properties dialog box.
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 files
to update your virus definition files, 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 diskette without using
the Emergency Disk creation utility. Is there anything
I need to do to be sure that it will work properly?
A: To enable your own Emergency Disk, 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 DOS directory or, if you
are using Windows 95 or Windows 98 system files, add
HIMEM.SYS from the \WINDOWS directory to the
boot diskette.
Note: For detailed instructions on creating an Emergency
Disk, refer to the instructions outlined in VirusScan
User's Guide, which you'll find on the Network
Associates website.
Q: I moved a .VSC file to my Startup folder. Whenever I
turn on my computer, VirusScan starts, but does not
begin scanning. How can I make VirusScan start scanning
automatically?
A: You need to customize your options. Follow these
steps:
1. Location the .VSC file you saved.
2. Right-click the .VSC file, then choose Properties
from the shortcut menu that appears.
3. Click the Detection tab.
5. Select the Start Automatically check box.
6. Click OK to close the properties dialog box.
Q: When VirusScan starts, how does it determine its
default settings?
A: VirusScan reads its default settings from the
DEFAULT.VSC file located in the installation directory.
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: An error occurs when VirusScan has completed 95 percent
of its installation. Why does this occur on my system,
but not on others?
A: Using a non-standard Windows 95 Winsock will cause the
Setup to fail on some systems at the 95 percent
completed point. To prevent this, use the default
Windows 95 Winsock.
Q: I removed the Recycle Bin from the VirusScan exclusions
list. How can I replace it?
A: Because the Recycle Bin is a system folder, it cannot
be added to the exclusions list using VirusScan's
browse feature. To restore it to the list, enter the
Recycle Bin's full path in the exclusions list:
\Recycled\
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
Windows taskbar. This is due to a limitation of
Exchange. Please refer to your Exchange documentation
for instructions on how to place these icons onto the
taskbar within Exchange.
