VNmacro v1.01d - 1 October 1996
Copyright (c) 1996 Safetynet, Inc. Portions (c) Frisk Software Int'l.
----------------------------------------------------------------------
VNmacro provides virus detection and disinfection of MS Word macro
viruses. According to recent Virus Bulletin statistics, a macro virus
is now the most prevalent virus type, with the Winword Concept virus
accounting for 14.2% of all virus infections (July 1996 survey).
VNmacro supports Microsoft Word 6+ and Excel file formats, and will
quickly detect and remove macro viruses. Its Windows interface
makes its operation simple, even for novice users.
VNmacro is part of the VirusNet anti-virus solution from
Safetynet, Inc. VirusNet protects Windows NT, Windows 95, Windows 3.x
and DOS PCs. Its network version centrally manages and distributes
virus protection to all workstations. Supported networks include
Netware, NT Advanced Server, Vines, Pathworks and Warp Server.
Complete evaluations of VirusNet PC and VirusNet LAN are available
for downloading from our WWW site. In addition, for your security
concerns, our StopLight family of software protects Windows 95,
Windows 3.x and DOS PCs. Stand-alone and network versions are
available for downloading from our WWW site.
Test Results
------------
A comprehensive Macro Virus scanner test was completed by Norman Hirsch
and Associates on 9/18/1996. It tested anti-virus products from McAfee,
Symantec, Safetynet, Dr. Solomon and TouchStone/Trend. The scanner
detection and cleaning results for 39 macro viruses are as follows:
Scanner Detected % Cleaned (out of 39)
---------------- ---------------------
Safetynet - VirusNet VNmacro 38 98% (38)
Dr. Solomon - AntiVirus Toolkit 32 87% (34)
McAfee - VirusScan 35 82% (32)
Symantec - Norton AV 29 74% (29)
TouchStone - PC-Cillin 38 23% (9)
Full test results are available at http://www.safe.net.
Installation Notes
------------------
1. Copy the VNmacro files to a directory on your hard drive or network.
2. Copy CTL3DV2.DLL to the Windows SYSTEM directory
3. Remove CTL3DV2.DLL from the VNmacro directory
Note: If CTL3DV2.DLL remains in the VNmacro directory, it will
display the following error message:
"This application uses CTL3DV2.DLL, which has not been
correctly installed. CTL3DV2.DLL must be installed in the
Windows system directory."
Operating Instructions
----------------------
Note: Before using VNmacro to scan for viruses, close any DOC files
that are open in Word for Windows. Otherwise, a "Sharing
Violation" message will be displayed in the report and the
file will not be scanned.
1. Start VNmacro by running VNMACRO.EXE.
2. Select the "Scan" button to display a screen of scanner options.
3. Type in or choose the "Scan Directory" button to select the location
to scan.
4. Choose whether to scan subdirectories under this directory.
5. Select to scan "Word documents" or "All files". Usually
"Word documents" is sufficient unless you have saved DOC files
with different file extensions.
6. If a virus is found, select whether to prompt before disinfecting
each file, disinfecting automatically or simply generating a report.
7. Select "Report all scanned documents" to show a list of all files
scanned.
8. Select the "Report File" button to locate the directory to save
the report file, or type the location and file name manually.
9. Select whether an existing report file should be overwritten with
the new report or appended.
That's it! Select OK to begin the scan or Cancel to return to the
main VNmacro screen.

Known problems
--------------
- The Daniel, Gangsterz, Phardera, Outlaw.A and Outlaw.B viruses are
not disinfected perfectly: after disinfection, the user has to open
every disinfected document with Word, select
Tools/Customize/Keyboard/Reset All, then Tools/Customize/Menus/Reset
All, and save the document back to disk. This is because these
viruses make somewhat unusual modifications to the documents they
infect. We know how to make the disinfection perfect but just didn't
have the time to implement it for this release.
- VNmacro causes a GPF when scanning some documents. This is not our
problem. The documents are corrupted and Word (or any other
OLE2-enabled application) will crash when opening them too. The bug is
in Microsoft's STORAGE.DLL. A future version of VNmacro will avoid
using this DLL.
- VNmacro scans only OLE2 files. As a consequence, it will not detect
WordMacro viruses or Trojans in Word 2.0 documents. The format of
these documents is different than the format of the documents
produced by Word 6.0 and above, especially concerning the macro
structures. Microsoft still has not provided us with information
about these differences. If you don't like that VNmacro cannot scan
for Word 2.0 viruses - complain to Microsoft. Word 2.0 viruses like
Polite can migrate to Word 6.x documents, however. Once this happens,
VNmacro will be able to detect the virus.
If any bugs are found, please report them to support@safe.net, and if
you have any suggestions for improvements - feel free to e-mail to the
above address.
