HyperText VSUM X9203 READ_ME.1ST
With the June, 1991 release, the Virus Information Summary List
was converted from its original ASCII list format into a custom,
hypertext database format. With the new format, the product name has
been changed to HyperText VSUM. The previous ASCII list product has
been discontinued, and will no longer be updated.
Why the change to a hypertext database? The original ASCII format
had become extremely large and unwieldy, it was difficult for most
people to effectively use. Printing also had become a problem unless one
had a very high speed laser printer. More importantly, the information
presented in the ASCII version was never really intended to be read
sequentially as a book, but instead to be a reference book or
encyclopedia.
The hypertext database version, HyperText VSUM, solves
these problems. There is no longer a need to print out the entire
document in order to be able to quickly locate a virus entry. Individual
virus entries, once selected by the user, can be printed by pressing
F4. HyperText VSUM also supports direct links between related
viruses and theor individual virus entries. The Common Name Cross
Reference from the ASCII version has been linked to allow direct access to
the virus entries by the common names. Four additional cross references
were initially added in the Appendices section: Length Cross-Reference and
Origin Cross-Reference on the Appendices menu, as well as Boot Sector
Infectors and Stealth & Sub-Stealth Viruses via the Viral Type
Cross-Reference selection on the Appendices menu. Additional cross-
references have been added as well, also located on the Appendices menu.
Virus entry format information can be found on the Appendices menu under
the selection "Virus Entry Fields".
HyperText VSUM is easy to use. Unzip your distribution file into
a directory on your hard disk, using PKUnZip version 1.10. Once unzipped,
type VSUM at the system prompt and press enter. The logo screen for
HyperText VSUM will be displayed. Press any key or the right mouse button
to go to the Main Menu. Pressing F1 will then present a four page tutorial
on the general display engine features. Selecting the Using VSUM entry on
the Main Menu will walk the user through looking up four different
viruses via different features of HyperText VSUM.
Please note that while the colors in HyperText VSUM can be altered
by the user, changed color attributes will be stored in the
VSUMX database. It will not be possible for you to return to the
exact original colors. It is also highly suggested that users backup
the VSUM.EXE program on a diskette and write-protect it. If you should
become infected, it ensures a clean copy to recover from.
There is one known incompatibility problem with HyperText VSUM. If
you normally operate your system with the graphic mode set to 50 lines,
you may receive a "Not enough memory" error when you attempt to run VSUM.
This problem is fixed by switching the display to 25 line mode.
The McAfee Associates' public domain VALIDATE program and its
documentation has been included with the VSUMX distribution file,
VSUMX203.ZIP. The Validate values for the VSUM engine and the VSUMX
database are:
File Name: VSUM.EXE File Name: VSUMX.H!
Size: 36,816 Size: 1,245,776
Date: 1-24-1991 Date: 3-27-1992
Check Method 1: 1BBB Check Method 1: 17F6
Check Method 2: 0600 Check Method 2: 0D67
If the values returned by Validate with your copy of HyperText VSUM
do not match the above, do not execute it as the program or database has
been altered.
Additionally, VSUMX203.ZIP has been archived with the verification
feature of PKZip. When you unzip this version, the following verification
information should be displayed:
# GTC898 Patricia M. Hoffman, Santa Clara, CA USA
If this information does not match your copy, please be aware that
the archive file may have been altered or corrupted.
All released versions of McAfee Associates' VCopy program, up to
and including V82 release, have a known false alarming problem when they
are used to copy the VSUMX.H! file. VCopy may falsely indicate that
VSUMX.H! is infected with the 1701 Cascade Virus [170x]. This is a true
false alarm, and has been reported to McAfee Associates and myself numerous
times. Unfortunately, it is not possible for it to be fixed within the VSUM
linked hypertext database file. Releases of VCopy after V82 should have
this false alarm problem fixed.
