Version 2.42d released 4/05/95
This release fixes false positive virus indications in MSAV/CPAV products
as well as DM300, Neuroquila, and ViennaF.
Version 2.42c released 3/23/95
This release fixes a false virus indication for: Auspara4 and Shiny.
Version 2.42b released 3/17/95
1) Small addition to IM's scanner of a few more viruses including Diehard2
and a correction to the Ming detection algorithm.
2) Adjust alignment of text on IM's Option menu.
3) Allow IM to update integrity data in initialize mode even when
"Integrity Update" is set to Never.
4) Fix detection of Freddy2 in Cheyanne's INNOCULAN.EXE.
5) Corrected false positive of Auspara4 and Phalcon
Version 2.42a released 2/28/94
1) IM supports a new option to allow rapid screening of diskettes for boot
viruses. This is available through the Check menu as well as the
"/VB" command line switch. This also allows IM to read boot sectors
on diskettes that are unreadable to DOS. Researchers can use this
option when testing IM since IM will also check the boot sector for
partition sector (MBR) viruses.
2) New "Force update" option on the "Integrity update" options submenu.
Selecting this option or using the new "/UA" command line switch will
force integrity master to update integrity data for all files. Normally
IM will not update integrity data for what appear to be corrupted files
when it is running unattended.
3) When run from a diskette, IM will now automatically offer to change to
change to another disk.
4) New easier install. SetupIM will now offer a super fast install that
usually gets IM installed in under one minute.
5) IM tolerates a wild card spec on it's /P (disk and directory change)
parameter. This allows you to use IM with some programs that insist
on including a wild card with the directory to check. For example:
IMSCAND C:\DOS\*.* will scan all files in subdirectory \DOS.
6) SetupIM changed so it will correctly recognize drive characteristics of
disks using Symantec's Ncache.
7) IM will not pause even if severe hardware errors occur when the /ND
command line option is used.
8) IM identifies over 600 new viruses by name and characteristic
including: 7thSon2, Ambalama, Andromeda, Ansibomb, AntiCleric,
Asexual, Attitude, Aurea, Blinky,BNB, BigX, Big_Bang, Bloody_Warrior,
Breaking, CarpeDiem, Centenary, Click, DA'BOYS, Dementia, Dichotomy,

and Vienna related viruses.

Version 2.31c released 11-22-94 (Bug fix release)
Fixes false-positives of StonedN,ArcvD,Hbex and 388 in memory.
Version 2.31b released 10-22-94 (Maintenance release)
1) Fix false indications of A_Totoro and Grog3 in some .EXE files.
These were partial false-positives since IM indicated that these viruses
would infect only .COM files. (False indication of ICE9 also fixed.)
2) In memory detection of Antique corrected.
3) Paula and Digital93, two viruses in the wild in South America added.
4) Update of international agents list.
5) New GENVIR.EXE. The prior version created a .bin that was being
detected by FPROT as a virus.
Version 2.31a released 10-01-94
1) New /ND parameter allows even faster execution of IM in unattended mode.
This works the /NE parameter but eliminates further pauses and screen
displays.
2) The primary display has been simplified and now displays license
information.
3) You may now choose report filespecs (disk, directory and filename) of
up to 30 characters using the /RF= command line option.
4) IM now supports a home directory so you can keep autonamed reports and
reload files in a single subdirectory.
5) Integrity Master now supports an option to never update integrity data
under any circumstance.
6) Registered users of IM can now download evaluation (shareware) versions
from any of thousands of BBSes world wide and convert them to the
registered version.
7) IM identifies over 300 new viruses by name and characteristic including:

mte in DECRYPT.EXE a program to use PGP in mailreaders).
2) Improved exmplanations included with CMOS checks
3) IM has been verified to detect all SMEG polymorphic viruses including
the new version of SMEG (Pathogen and Queeg).

Version 2.21u released 04-25-94
This is a UK oriented release otherwise identical with 2.21b.
Version 2.21b released 04-25-94 (Maintenance release)
1) When used with the /NE switch and checking boot sector viruses
IM will require only one key-press whether a virus is found or not.
(Needed by researchers to test boot sector viruses using SIMBOOT)
2) The full report of boot sector viruses will be displayed even when the
"/1" command line option is used.
3) IM will consistently display a header before any checking even
if only a boot sector or CMOS is checked.
4) Detection of viruses using the SMEG (Pathogen) polymorphic engine.
5) Modification to accomodate some non-standard CMOS memories.
Version 2.21a released 02-9-94
1) Since many people are unaware that IM can be used as a simple virus
scanner, IM will now offer the choice of scanning or initializing
when it encounters a directory that it hasn't seen before. This menu
can be easily disabled.
2) IM will now offer several options if it encounters a corrupted file
(unless you have already told it what to do using the "Integrity Update"
submenu). This allows you to easily verify that corrupted files have
been correctly fixed.
3) IM offers several new command line options:
/F - Forces full integrity checking. This is useful if integrity
checking has been set to "Quick update" as default.
/NOB - No Beep. Turns sound off.
/Q - Forces "Quick Update" mode.
/REPA - Report All. This reports all files scanned during a virus scan
or all files added during an initialize. This option is useful
if you want to create a report showing all files and their
check values or if you are testing a virus collection.
4) IM's change command line option (/P) now allows you to include a disk
letter.
5) IM now includes batch files to illustrate its use to automatically scan
diskettes and new uploads. SYSOP.DOC includes further information on this.
6) We now offer registered users 12 months of free downloads of the
registered version.
7) We have eliminated false-positives with respect to Central
Point/MicroSoft anti-virus related programs.
8) IM will now terminate if a virus is found in memory. (This can be bypassed
with the /B option.)
9) IM includes a description (NET.DOC) of how to easily install and use IM
on a LAN.
10) We fixed a problem which would cause repeated or lost lines on the
report file and another bug which could cause IM to halt when
checking some Syquest removable media boot sectors.
11) IM identifies over 350 new viruses by name and characteristic.
