VIRUSCAN
Version 76 of VIRUSCAN adds 18 new viruses, bringing the
total number of known computer viruses to 239, for a total of 501
viruses including strains. The enclosed VIRLIST.TXT file outlines
the characteristics of the new viruses. For a comprehensive
discussion of each of the viruses, we recommend that you access the
VSUM document copyrighted by Patricia Hoffman. It is available on
most bulletin board systems.
In addition, two new command line options have been added to
improve batch mode operation of SCAN: The /NOPAUSE option turns
off the screen pause that occurs when SCAN fills up a screen with
messages. The /NOBREAK option will prevent SCAN from stopping when
a Control-C or Control-Break is issued.
CLEAN-UP
Version 76 adds nineteen viruses to the list of computer
viruses that can be safely removed. They are the 555, 651, 3066,
Air Cop, Beeper, Black Monday, Den Zuk, Fellowship, Filler, Ghost
Korea, Lazy, Lisbon, Mardi Brothers, Murphy, Print Screen-2, RPKS,
Striker, and Typo Boot viruses. For more information about these
viruses, please refer to the accompanying VIRLIST.TXT file.
Additionally, a new command, /NOPAUSE, has been added. When
CLEAN is run with the /NOPAUSE option it will not stop when it
fills the screen with messages.
VSHIELD
Version 76 has been completely re-structured to provide a
major increase in the execution speed. Version 76 will run twice
as fast as previous versions. The amount of time added to program
loads will now be cut in half.
Version 76 of VSHIELD adds 18 new viruses, bring the number
of discrete computer viruses detected to 239 and the number of
variants to 501 viruses.
Version 76 of VSHIELD adds two new options, /WINDOWS
option and /CHKHI. When run with the /WINDOWS option, VSHIELD
will intercept viruses in DOS processes under Microsoft Windows.
The /CHKHI command allows the scanning of the high memory area
present on 286 and 386 machines.
NETSCAN
NETSCAN Version 76 adds nineteen new viruses. For a listing of
complete listing of viruses, refer to the VIRLIST.TXT file.
Version 76 of NETSCAN adds a critical error handler that allows
NETSCAN to continue scanning if a file-open error occurs. For more
information about the /UNATTEND option, see the COMMANDS section.
NOTE: For Version 76 of the documents, the synopsis of new
viruses that usually appears was removed for space
reasons. I'd like to know if people would prefer to
have a brief listing (1/2 page) of the viruses in the
documentation or not. Please respond by email.
