WHAT IS A VIRUS UPDATE FILE?
Virus Update files contain up-to-date virus signatures and other information for Virex to use to protect your computer against the thousands of computer viruses in circulation and against the hundreds of new viruses that emerge between updates. Network Associates releases new Virus Update files each month. To protect yourself against these virus threats, download and install the latest Virus Update file every month.
DOCUMENTATION
Network Associates provides each of its products with an extensive set of documentation, which usually consists of one or more product guides saved in Adobe Acrobat Portable Document Format (.PDF), and an online help system, whose form can vary, depending on the platform on which the product runs.
Acrobat .PDF files are flexible online documents that contain hyperlinks, outlines and other aids for easy navigation and information retrieval. You can also install an Acrobat plug-in file that allows you to read .PDF documents from within your web browser while online. Copies of the product documentation come with the product CD-ROM or are available on the Network Associates website at:
ftp://ftp.nai.com/pub/manuals/total_virus_defense
A copy of the latest version of the free Acrobat Reader also comes with the product CD-ROM, or you can download the latest English-language version from the Network Associates FTP site at:
ftp://ftp.nai.com/pub/manuals/acrobat_reader
To download other Acrobat Reader versions, visit the Adobe website at:
IMPORTANT: Most Network Associates TVD product documentation produced during and
after September 1999 requires the use of Adobe Acrobat Reader v4.0.

NEW FEATURES
The v4130 engine includes these enhancements and new features:
* Improved performance for Microsoft Visio file scanning
The engine's scanning speed for Visio files has been improved.
* Additional support for Microsoft Office 2001 for Macintosh.
The engine can now detect unknown viruses within Visual Basic Scripts.
Some viruses can conceal Visual Basic Scripts within the body of an e-mail message. Some Windows and Internet Explorer configurations allow the embedded script to run when the e-mail message is opened in Microsoft Outlook.
* Improved renaming of infected files
Previously, files with a file extension of .V?? were not renamed. They are now renamed with a .VIR extension. See the guide that comes with your product for full details.
INSTALLATION
Network Associates distributes Virus Update files as StuffIt archives. These come in two forms: a BinHexed VX010101.HQX file, and as VX010101.UPD, a straight archive file suitable for use with the eUpdate feature in Virex anti-virus software v6.0 and later.
• USING EUPDATE TO INSTALL VIRUS UPDATE FILES •
If you use the eUpdate feature in the Virex v6.0 or later software, the software itself will download, extract, and install the Virus Update file. Although this works quite well for individual Macintosh computers, Network Associates recommends a different approach for medium and large networks.
With this method, you use a web browser or FTP client software to download the VX010101.UPD file directly from the Network Associates FTP site. You then post the file to a central server on your network and configure all of your client computers to download the VX010101.UPD file from that central server via FTP or AppleTalk, depending on your preference or your network configuration.
This allows you to control when all updates occur, to reduce network traffic on your servers, to reduce your security risks from outside your network, and to take best advantage of Network Associates server bandwidth. For more details, see the Virex User's Guide stored on the Virex CD-ROM or disc image.
• INSTALLING VIRUS UPDATE FILES DIRECTLY •
To install Virus Update files directly on to each of your client Macintosh computers, download the VX010101.HQX file from the Network Associates website or FTP site, then extract the files for installation. To do so, you'll need a copy of StuffIt Expander, StuffIt Lite, or another utility that can read and process files saved in StuffIt format.
You can download the utilities you need from most electronic services. Most browser software also includes a plug-in version of StuffIt Expander that can extract the files automatically, as soon as you download them.
NOTE: If you have Virex anti-virus software v6.0 or later installed, you can
use its eUpdate feature to download and install new Virus Update files
automatically. To learn how to do so, see the Virex User's Guide.
To install the Virus Update file, download or copy the compressed file to your Macintosh desktop or to a temporary folder on your hard disk. Next, follow these steps:
1. Start your compression application, then use it to open
and extract the Virus Definitions 2001-01-01.sit file.
If you have a copy of StuffIt Expander on your desktop,
you can simply drag the Virus Definitions file on top of
StuffIt Expander to have the file extract automatically.
2. The extracted file will appear on your hard disk with the
name Virus Definitions 2001-01-01. Double-click this file
to start Virex.
Virex will ask you to confirm that you want to update your
Virus Definitions file.
3. Click Update to continue.
Virex will tell you when it has finished updating your file.
4. Click OK to return to the Virex application's main window,
where you can immediately start a new scan operation.
In the lower left corner of its main window, the Virex application displays the legend Virus Definitions, followed by a date. This date marks the day Network Associates produced or designated this update file for release. For the January 1, 2001 Virus Update, this date is 1/1/01. The specific format of the date shown will depend on how you have your computer set to display dates.
NOTE: By default, the Virex Installer uses the Virus Definition file that comes
with it to scan your system. You should consider replacing this Virus
Definition file with a current Virus Update file in order to take advantage
of new detection capabilities.
ADDITIONAL INFORMATION
• AUTOSTART WORMS •
If Virex detects an AutoStart worm on your computer, Network Associates strongly recommends that you restart your system with extensions disabled, then start a scan operation with the Virex application.
To disable your extensions, press the Shift key on your keyboard as you restart your computer. Continue to hold the Shift key until you see the message Extensions Disabled. This prevents the AutoStart worm from loading into your computer's memory and allows Virex to remove it from your system. If you do not disable your extensions, the worm will load into memory and can continue to spread even after you remove its original files from your system.
As an alternative, follow these steps:
1. Choose Virex Control Panel from the Apple menu to
open the control panel window.
2. Click Preferences.
3. Select the General icon at the left of the Preferences
dialog box, then choose either First or Alphabetically
from the Load Control Panel menu.
4. Select the File Access icon at the left of the
Preferences dialog box.
5. Verify that the Scan Files When Opened checkbox is
selected.
6. Click Save to save your settings and return to the
Virex Control Panel window.
7. Close the Control Panel window, then restart your
computer.
Virex will load into your computer's memory first and will remove the worm as it tries to launch at startup.
To prevent the AutoStart worm from reappearing on your computer or infecting other computers, use Virex to scan all disks that you might have used with an infected computer. If you have the Scan Files When Opened option activated in the Virex Control Panel, you can safely mount infected disks for scanning.
If you need to enable additional extensions in order to mount some disk types, you should disable the AutoPlay option in the QuickTime Settings control panel before you restart your computer. Follow these steps:
1. Choose QuickTime Settings from the Apple menu to
open the control panel window.
2. Choose AutoPlay from the menu at the top of the
control panel window.
3. Verify that the Enable Audio CD AutoPlay and the
Enable CD-ROM AutoPlay checkboxes are clear.
4. Close the control panel window.
5. Use Extensions Manager or an extensions manager
utility to enable the extensions you need, then
restart your computer.
NEW VIRUSES DETECTED AND REMOVED

UNDERSTANDING VIRUS NAMES
Network Associates anti-virus software typically follows industry-wide naming conventions to identify the viruses that it detects and cleans. Occasionally, some virus names deviate from strict industry standards.
The first virus with a given set of characteristics that mark it as a distinctly new entity receives a "family" name. Virus researchers draw the family name from some identifying quirk in the virus--a text string, perhaps, or a payload effect.
Names for variants of that first virus consist of the family name and a suffix--<VIRUS>.A, for example. The suffix designations continue in alphabetical order until they reach .Z. At that point, they begin again with .AA and continue until they reach .AZ. Still later variants receive the suffix .BA through .BZ, and so forth, until the suffix designations reach .ZZ. If yet another variant appears after that, it would get the suffix .AAA.
As new virus strains appeared, industry naming conventions evolved to include more information. Some names, for instance, include parts that identify the platform on which the virus originated or can run. Macro viruses, the most prevalent of the virus types, can have a complex names that consists of a number of parts. Although the virus name might identify the platform of origin, most macro viruses are cross-platform and can run in a number of different environments. The effects of a virus infection can vary between platforms, but in a networked environment, what might have no effect on one platform can do severe damage in another.
Among anti-virus vendors, virus names can include:
• PREFIX •
The prefix designates the type of file that the virus infects or the platform on which it can run. Network Associates virus names can include these prefixes:
A97M/ Macro virus. Infects Microsoft Access 97 files
HLL/ File-infector or boot-sector virus. Written in
a high-level programming language
HTML/ Script virus. Infects HTML files
IRC/ Internet Relay Chat script virus. This virus
type can use early versions of the mIRC
client software to distribute a virus or
payload
JS/ JavaScript virus or Trojan horse program
O2KM/ Macro virus. Infects Microsoft Office 2000
files
PP97M/ Macro virus. Infects Microsoft PowerPoint 97
files
VBS/ Script virus. Infects Visual Basic scripts
W32/ File-infector or boot-sector virus. Runs in
32-bit Windows environments (Windows 95,
Windows 98 or Windows NT)
WIN/ File-infector virus. Runs in 16-bit and 32-bit
Windows environments (Windows 3.1x, Windows 95,
Windows 98, or Windows NT)
W95/ File-infector or boot-sector virus. Runs in
Windows 95 and Windows 98 environments
W97M/ Macro virus. Infects Microsoft Word 97 files
WM/ Macro virus. Infects Microsoft Word 95 files
X97F/ Macro virus. Infects Microsoft Excel 97 via
Excel formulas
X97M/ Macro virus. Infects Microsoft Excel 97 files
XF/ Macro virus. Infects Microsoft Excel 95 or 97
via Excel formulas
XM/ Macro virus. Infects Microsoft Excel 95 files
• INFIX •
These designations usually appear in the middle of a virus name. Network Associates assigns these designations, which will differ from industry conventions.
.CMP. Companion file. This designates a companion
file that the virus adds to an existing
executable file. Network Associates
software deletes the companion file to
prevent later infections
.MP. Multi-partite virus. A Network Associates
designation
.OW. Overwritten. This identifies a file
irreparably corrupted when a virus
overwrote data within it. This file must
be deleted.
• SUFFIX •
These designations usually appear as the last part of a virus name. A virus name can have more than one suffix. One might designate a variant, for example, while others give additional information. Network Associates assigns many of these designations, which can differ from industry conventions.
@MM Mass mailing distribution. This virus might
use standard techniques to propagate itself,
but it will also, or in some cases primarily,
use an e-mail system to spread
.A to .ZZZ Virus variant designation
.APP Appended viruses. This designates a virus that
appends its code to the file it infects, but
that fails to provide for correct replication.
Network Associates software detects these
files in order to prevent false virus
identifications
.CAV Cavity virus. This designates a virus that
copies itself into "cavities" (areas of all
zeroes) in a program file.
.CLI Client-side component of an Internet Trojan-horse
program.
.DAM Damaged file. This designates a file damaged
or corrupted by an infection
.DR Dropper file. This file introduces the virus
into the host program
.GEN Generic detection. Native routines in Network
Associates software detect this virus without
using specific code strings
.GR Generic detection and removal. Native routines
in Network Associates software detect and
remove this virus without using specific code
strings
.INTD "Intended" virus. This designates a virus that
has most of the usual virus characteristics,
but cannot replicate correctly. Anti-virus
software will detect it in order to prevent
false identifications of active viruses
.SVR Server-side component of an Internet Trojan-horse
program.
