The IBM Anti-Virus Product, Version 2.1.2
Copyright (C) IBM Corporation 1989, 1990, 1991
The following are the highlights of the changes and enhancements made
to The IBM Anti-Virus Product since the release of Version 2.00.01:
- Added signatures for approximately 42 viruses (refer to VIRSCAN.DOC,
section 5.1, for more details)
- VIRSCAN now looks for the local message file "local.msg", in the same
directory as "virscan.exe", and if it is found, virscan displays it
upon exit (in addition to the standard messages) when one or more
virus signatures are found. A maximum of 10 message lines are displayed.
This facility allows sites to tell users about local procedures that
should be followed when viruses are encountered.
- Added support for arbitrary-length "don't-cares". "%N" sequences (in
place of a pair of bytes in a signature) mean that 0 to N arbitrary
bytes can be in the corresponding position. 'N' is a single hex digit
from '0' to 'F'.
- Spaces are now allowed between pairs of hex digits in VIRSCAN signatures.
This can simplify the use of signatures from other sources.
- VIRSCAN now respects the "boot" keyword that can be used in the third
line of virscan signatures. If a "boot" virus is found in a file, the
user won't by default be warned unless the third signature line also
contains the strings "EXE" or "COM" (or both). If the -G command line
option is specified, then the user will be warned of boot virus
signatures wherever they are found.
- VIRSCAN now won't complain if it can't read the boot sector of a network
drive, unless the '-v' option is used or the boot sector scan was
explicitly specified with the '-b' option.
- Added the "*" option:
"*" scans all local fixed drives.
"*n" scans all network drives.
"*f" scans all local fixed drives.
"*fn" scans all local and network drives.
For instance, try
virscan *
to scan all local fixed disks.
- Improved the speed of the memory scan.
- Documented the -NB option.
