         ====================================================


This list is simply designed as a handy cross-reference listing to aid in
the study and classification of viruses. Data is continually being added to
the database and future versions will be released into the Public Domain on
a monthly basis or as warranted by the amount of changes that are implemented.
Future versions will be released in the VXRFmmyy.ZIP format, (VXRFmmyy.SDN
via SDNet/Works!), where "mm" and "yy" is the month and year, respectively.
Please keep in mind that there are some viruses that are not listed here due
to their unavailability for analysis, not being outlined in other reports or
the samples that we have studied do not actually replicate. Future releases of
this cross-reference will incorporate them whenever possible. This document
may be freely distributed, granted that it is done so in it's original,
unaltered format.

Viruses referenced are listed by the resultant file growth. Overwriting
viruses are referenced by simply the effective length of the virus.
Comments contained within the "Type" column are generalized descriptions of
the virus characteristics.

Special thanks to: Wallace Hale, David Grant, Righard Zwienenberg,
                   Glenn Jordan, and Ross Greenberg.
