THE VIRUS TERMINUS(c) is an intelligent SHELL Menu utility program
for McAfee Associates Anti-Virus programs VIRUSCAN, CLEAN, and VALIDATE.
VIRUS TERMINUS is menu driven and may be used with a mouse or keyboard.
The SCAN/CLEAN option switches have been made visible and can be toggled
through an easy to use interface. Reports may be viewed, printed, merged
or deleted. Virus Fact Sheets allow the user to obtain information on
virus infectors such as the known characteristics, areas of damage, the
McAfee Associates disinfection program needed, etc. A quick program
self-test is available and there are a variety of options including
screen saver, options lock with password, mono video mode, etc.
Virus Terminus v4.6 supports SCAN/CLEAN's advanced IMMUNIZATION and
RECOVERY functions. These functions provide protection with recovery
after detection from new or unknown virus infectors.

***** GENERAL OPERATION RESTRICTIONS:
DO NOT run The Virus Terminus from the hard disk if your system
is already infected. Read Page #4 for disinfection sequence.
DO NOT use the Virus Terminus in any environment or on any
machine where another virus disinfector utility is currently installed
and running. This includes but is not limited to TSR virus utilities.
No claim is made herein or otherwise as to compatibility with other
author/program virus disinfector & detector utilities.
The Virus Terminus was designed to run in a stand-alone PC
environment. This does not include use in LAN environments, etc.
Users should make every effort to use only the most recent
versions of SCAN or CLEAN. Version 4.6C of The Virus Terminus was
tested with CLEAN 8.9B97 and SCAN 9.0v99
- PAGE 4 -
***** TYPICAL DISINFECTION SEQUENCE:
* It is strongly recommended that you get experienced help in *
* dealing with computer virus infection. *
* The outlined procedure below is a suggested typical disinfection *
* sequence. This procedure may vary depending on the extent and *
* type of computer virus infection being dealt with. These *
* instructions are not meant to replace those which are found in *
* the documentation for SCAN and CLEAN. *
DO NOT RUN THE VIRUS TERMINUS FROM A HARD DISK if your
system is already infected. Use the following steps for best
results:
1. Power Down your system. DO NOT reset your computer by
pressing CTRL-ALT-DEL or the hardware reset button!
2. Boot from a KNOWN NON-INFECTED WRITE-PROTECTED DOS SYSTEM DISK.
3. Use the floppy installation procedure for systems already
infected as outlined on page #6 . Perform a SELF-TEST .
4. SCAN your hard disk to determine which and/or how many virus
infections may be present. Make sure MEMORY SCAN is toggled ON.
5. CLEAN - Disinfect your hard disk. Use the virus ID code previously
reported by SCANand make sure MEMORY SCAN is ON. Do a SELF-TEST.
NOTE: If you are unable to access your hard disk after booting
from a floppy, check to make sure that any special device
drivers needed to use the hard disk are on the floppy and
run from the CONFIG.SYS or AUTOEXEC.BAT file.AT THIS POINT
IF YOU HAVE NOT DONE A BACKUP OF ANY CRITICAL FILES ON YOUR
SYSTEM, THEN DO SO IMMEDIATELY.
If more than one virus type was detected, then CLEAN-UP will
have to be run for each type of virus.
6. Power down the system after CLEANing your hard disk.
7. Check your hard disk once again with SCAN to make sure you
were successful in disinfecting the system. If not, repeat
steps #1, 2, 4, 5, 6 and 7 all over again.
8. Now, check any floppies that may have been inserted into
your drives to determine if they are infected. If so,
follow the directions in the CLEAN documentation to
disinfect. Power Down your system when finished.
9. SCAN your Hard Disk once again to make sure you have not
reinfected your system. Make sure MEMORY CHECK is toggled ON.
Perform a SELF-TEST.
Failure to disinfect floppies previously used in an infected
system may lead to virus reinfection.

***** INSTALL THE VIRUS TERMINUS(c): ( NON-Infected System Only! )
THE VIRUS TERMINUS(c) operates most efficiently when
used in conjunction with a hard drive. You may also run
this program from a floppy drive when your hard drive is
infected.(360K, 720K, 1.2MEG, 1.44MEG disk size) Please read
page #8 for information on 360Kb installation SCAN/CLEAN disk
swapping. Current program sizes still allow installation on a
single 360Kb DSDD disk!
McAfee Associates files : SCAN.EXE; CLEAN.EXE; VALIDATE.COM;
VIRLIST.TXT
VIRUS TERMINUS files : VT46C.EXE; VTCF1.EXE; VTCF46.EXE
--------------------------------------------------------------
HARD DRIVE: 1. Create one subdirectory for SCAN,CLEAN,VALIDATE,
VIRLIST.TXT, and THE VIRUS TERMINUS.
(Separate directories are allowed for SCAN, CLEAN
, VALIDATE, AND VIRLIST.TXT - Hard Disk only!)
2. Copy McAfee Associates FILES and VIRUS
TERMINUS files to the subdirectory*
* 3. Change the current drive and subdirectory to the
location of The VIRUS TERMINUS and then run the
file VT46C.EXE. Press <ENTER> after typing each
of the following lines.
C:
cd\location
vt46C.exe
C: may be D: or whatever drive you installed
The VIRUS TERMINUS program on. cd\location
may be cd\utility\viruscan or any subdirectory
where you placed the TERMINUS files.
4. Press F5 to configure when you reach the Main
Menu.
------------------------------------------------------------
FLOPPY : 1. Format blank disk.(360K, 720K, 1.2Meg, 1.44Meg)
2. Copy McAfee Associates and VIRUS TERMINUS
files to the disk. Copy your shell or
file utility to the disk if there's room.
DO NOT copy the Virus Terminus files
to a subdirectory on your floppy
disk. Place ALL files in the ROOT directory.
- PAGE 6 -
* 3. Place this disk in DRIVE #A or DRIVE #B
A:
cd\
vt46C.exe
or
B:
cd\
vt46C.exe
Press F5 to configure at the Main Menu.
The first time you run VT46C.EXE make sure you go no further
than the MAIN MENU before you press F5 and make the needed additions
or corrections to the DEFAULT TABLE.
*********************************************************************
The CURRENT DRIVE and SUBDIRECTORY must be the location of the
VIRUS TERMINUS file set. Failure to change over to the TERMINUS
drive and subdirectory will cause you to have to re-configure
and modify the default table each time you run the program. The
default table is always loaded in from the current drive and
subdirectory at the time you start-up The VIRUS TERMINUS.
You may create a DOS BATCH file with the loading sequence
previously outlined in HARD DRIVE step #3 and FLOPPY step #3
installation instructions.
*********************************************************************
***** INSTALLATION FOR SYSTEMS ALREADY INFECTED *****
!! POWER DOWN your system first !!
!! DO NOT -USE CTRL-ALT-DEL KEY RESET SEQUENCE !!
!! DO NOT -PRESS THE RESET BUTTON !!
1. Turn your system on and BOOT from a known non-infected DOS
disk.(Place the DOS system disk in drive #A - WRITE PROTECT)
DO NOT MAKE THE MISTAKE OF LEAVING AN INFECTED FLOPPY IN
THE BOOT DRIVE.(READ ABOVE!)
2. Format a blank disk using the DOS format command. Use the
FORMAT.COM file found on your non-infected DOS disk. Avoid
accessing or using any files and utilities found on your
hard disk. Format the highest capacity floppy your system
drives will allow. Current program version sizes allow 360K,
720K, 1.2MEG, 1.44MEG disk sizes.
3. Follow these guidelines for the drive specification that
you are using:
A. Copy SCAN.EXE, CLEAN.EXE, VALIDATE.COM,
VIRLIST.TXT to the newly formatted disk.
- PAGE 7 -
B. Copy VT46C.EXE, VTCF1.EXE, and VTCF46.EXE
to the newly formatted disk. DO NOT put these
files in a subdirectory on your disk. Put ALL
files in the ROOT.
C. Place this disk in DRIVE #A or #B and type
each of the following lines pressing <ENTER>
after each:
A:
cd\
VT46C.EXE
or
B:
cd\
VT46C.EXE
D. Press F5 as soon as you are in the main menu
and configure VIRUS TERMINUS.
E. NOW write protect the disk!
F. Select #7 at the MAIN menu to run a Self-Test
to make sure the installation did not infect
your work disk AND/OR computer RAM memory.
***** NOTE: Your configuration file vt46C.cfg will be ignored if
any of the directory paths specify a drive other than
A: and/or B: when running Virus Terminus from a floppy.
The configuration and defaults will be initialized as
when the program is first run. This is a safety mechanism
to help insure that you do not access or run any programs
on your hard disk while trying to disinfect same.
***** NOTE: The Report option of SCAN and CLEAN will not work
since you will have write protected the disk. All
requests to SCAN/CLEAN single or job batch files
will be directed to the ENTIRE SUBDIRECTORY.Terminus
must make a temporary file named OPTIONS.$$$ on
your disk when you are in the SCAN/CLEAN FILE(s)
submenu. This will be impossible if your floppy
is write protected! Instead, when your disk is
write protected, Terminus sends SCAN/CLEAN a set of
command line options which include the name of the
of the subdirectory you select. ( \*.* instead
of individual file names.)
- PAGE 8 -
***** 360Kb Installation, DISK SWAPPING, ALTERNATE SOLUTIONS:
Disk swapping is forced on when the startup option /D
is detected. This mechanism allows the creation and use of two or
three installation disks with appropriate prompts issued to the
user indicating which disk to put in the drive during runtime.
DISK #1 - vt46C.exe, vtcf1.exe, vtcf46.exe, validate.com and
virlist.txt
DISK #2 - scan.exe and clean.exe
or
DISK #2 - scan.exe DISK #3 - clean.exe
Note that it is also possible to create, with current program sizes
of SCAN/CLEAN 8.9B97, the following alternative disk installation:
DISK #1 - vt46C.exe, vtcf1.exe, vtcf46.exe, validate.com,
virlist.txt, scan.exe, and clean.exe
The following program functions are disabled when disk swap is ON:
1. SELF-TEST including startup SELF-TEST (/T)
2. Startup LOCK (/L) which includes SELF-TEST before program entry.
OPTIONS LOCK may still be activated from within the program.
3. SCAN/CLEAN report generation.
Disk swapping may be activated by adding the /D options at startup
time:
A> vt46C.exe D <Press ENTER>
It is possible in a two floppy system to use both drives when the
main objective is to scan or disinfect the hard disk. One disk/drive
would be utilized for The Virus Terminus programs plus virlist.txt &
validate.com, and the other for SCAN and/or CLEAN. The default table
should be modified to indicate which drive will contain SCAN & CLEAN.
There are other alternatives such as eliminating virlist.txt and
placing both SCAN.EXE and CLEAN.EXE with the Virus Terminus files
ALL on one 360Kb disk. The above installation tips are offered as
suggestions ... users may elect different variations as needed.
Disk swapping is offered as a solution to limited disk space
on those systems which employ a single 360Kb floppy drive and hard
disk where the intention is to SCAN and/or CLEAN the hard disk.
Despite the tendency of computer manufacturers to now market systems
with higher capacity floppy drives, many such systems still exist in
the work place today.
NOTE: Operating The Virus Terminus from a floppy imposes the
restriction that ALL program files, i.e. VT46C.EXE
VTCF46.EXE VTCF1.EXE SCAN.EXE CLEAN.EXE VALIDATE.COM
and VIRLIST.TXT must be located on a floppy - not the
hard disk. This is a safety mechanism to insure that
no programs will be run from a potentially infected
hard drive during a SCAN or disinfection sequence
thereby helping to reduce the possibility of further
infection by certain virus types.
- PAGE 9 -
You should not run any programs located on your hard drive
until you are sure ALL files and the entire system
has been disinfected!
**********
SUGGESTION: If your system is not infected it would be wise to make
********** up a disk like one of those previously described so that
if ever the need arises you will be prepared to meet any
virus infection threat without delay and inconvenience.
***** VIRUS TERMINUS START-UP OPTIONS:
/S = Check Snow - Use to clear up display - older CGA's
/M = Mono - Eliminates window background colors and makes
certain textcolor adjustments. Use with green/amber CGA,
gray VGA display, Laptop models, etc. Mouse will work
if present. DO NOT use with true IBM MDA(Monochrome).
/T = Start-up SELF-TEST - Checks Terminus file set, SCAN,
CLEAN, VALIDATE and MEMORY.
/L = Limit Operation to SCAN FLoppies ONLY! - forces Terminus
to proceed directly to the SCAN/CLEAN DRIVE(s) submenu,
OPTIONS LOCK forced on, only floppy drives given as choice
for SCAN or CLEAN, password required to continue if virus
infection is found, password needed to exit the SCAN/CLEAN
DRIVE(s) submenu. Also forces startup self-test. Read
Page #17 for more details.
/D = Enable SCAN/CLEAN program disk swapping.
/Q = Quiet mode - disable sound routines!
Implement as follows: (or any combination thereof)
A> vt46C.exe S (press ENTER) or A> vt46C.exe M (press ENTER)
A> vt46C.exe T (press ENTER) or A> vt46C.exe L (press ENTER)
A> vt46C.exe D (press ENTER) or A> vt46C.exe MTLSQ
***** RUN-TIME and START-UP SELF-TEST:
The Virus Terminus provides a quick and easy way to SELF-TEST
for possible infections. The Main menu selection #7 and F7-SELF-TEST
found in each submenu will scan memory and the Virus Terminus dir.
Start-up Self-Test for virus infections may be initiated as
outlined in the START-UP OPTIONS section above. The self-test will
be performed before program operation reaches the Main Menu. An
orderly program HALT is available if a virus infection is found.
NOTE: SCAN and CLEAN also perform their own self-test each time
they are run.
- PAGE 10 -
***** CONFIGURE THE VIRUS TERMINUS:
THE VIRUS TERMINUS(c) may be configured from the main
program menu or any sub-menu while the program is running. It
is highly recommended that you configure your paths and
parameters when running the program for the first time. DON'T
RUN THE VIRUS TERMINUS FROM YOUR HARD DRIVE IF THE SYSTEM IS
INFECTED. Use the floppy installation and disinfect your drive
first - then install and run from your hard drive. Above all,
FOLLOW THE DIRECTIONS THAT CAME WITH SCAN or CLEAN. Here is an
explanation of the program default parameters:
VIRUS TERMINUS PRGM DIR: Directory where the VIRUS TERMINUS files
will be found.
SCAN.EXE PROGRAM DIR: Directory where SCAN.EXE is located at.
CLEAN.EXE PROGRAM DIR: Designates where CLEAN.EXE is located at.
SCAN/CLEAN REPORTS DIR: Same directory as TERMINUS PRGM DIR.
VALIDATE.COM PRGM DIR: Location of VALIDATE.COM
VIRLIST.TXT FILE DIR: Location of VIRLIST.TXT
DOS SHELL PATH & FILE : This parameter will describe where the
DOS Shell will be located and the name
of the shell program. Just enter the
directory and name of the program that
must be executed to make your shell work.
You may even use DOS COMMAND.COM if no
shell is available. When you press <F3>
the program control will go to the file
you specify.(HARD DISK INSTALLATION ONLY!)
EXP.VIRUS DAT.FILESPEC : Path and filename for the experimental data
to be used with SCAN. Please read the DOCS
that came with SCAN. ADVANCED USER FUNCTION!
EXP. VIRUS DATA ON/OFF : Set this switch to 'ON' and the experimental
virus data file will be used by SCAN. /EXT
Read further for more info. on Exp. Data
FRENCH MESSAGES ON/OFF : Turns on/off SCAN/CLEAN French messages. /FR
SPANISH MESSAGE ON/OFF : Turns on/off SCAN/CLEAN Spanish messages. /SP
DISABLE CTRL-BRK ON/OFF: Disable CTRL-BRK key combo during SCAN &
CLEAN operations. /NOBREAK
DISABLE MORE? ON/OFF: Disable SCAN/CLEAN MORE? prompt when screen
is full. /NOPAUSE
- PAGE 11 -
SCREEN SAVER ON/OFF: Enables screen saver. User given choice of
1 to 60 minute delay before Saver activates
START-UP OPTION LOCK: Set this parameter to ON if you wish to lock
options including access to the default table
each time the program is run. This mechanism
may be defeated during program operation by
pressing F6-OPTIONS LOCK and entering the
correct password. Read further for a list of
options which are locked for each menu. This
option forces a Self-Test at startup.
ADD SCAN PRGM OPTIONS : Enter options not available with The Virus
Terminus program. Clear by entering <SPACE>
ADD CLEAN PRGM OPTIONS : Enter options not available with The Virus
Terminus program. Clear by entering <SPACE>
* NOTE: The state of each switch can be changed after THE VIRUS
TERMINUS is up and running. This is the only area where the
options /FR, /SP, /EXT, /NOBREAK, and /NOPAUSE may be
activated.
***** ADDING NEW or EXTRA OPTION PARAMETERS:
Modify the default table entries designated as ADD SCAN PARAMETERS
and ADD CLEAN PARAMETERS. Refer to your SCAN.EXE and CLEAN.EXE
documentation for a list of valid parameter options.
***** USING A DOS SHELL UTILITY:(HARD DISK INSTALLATION ONLY!)
Just press F3 at any menu. THE VIRUS TERMINUS will suspend
operation while you are in your shell/utility. You can get
back to THE VIRUS TERMINUS by using the EXIT/QUIT function
of your utility or by typing 'EXIT' at the DOS command prompt.
DO NOT attempt to go back to THE VIRUS TERMINUS by re-launching
VT46C.EXE instead of using your SHELL's 'EXIT' function.
- PAGE 12 -
***** MOUSE OPERATION:
The two button Microsoft Mouse hardware specifications
are supported by this program when used in conjunction with a
color display/card that supports the IBM CGA C80 standard.
The program's video mode auto-detect logic disables mouse
operation if a Monochrome Display Adapter is detected. Only
keyboard entry is functional in MONOCHROME video mode(IBM MDA
standard). Logitech and all other Microsoft Mouse compatible
mice should function properly. The program logic checks for
a 'connected' mouse. You should not experience any trouble
if your mouse is truly MS compatible, connected to the
serial port or buss card, and the mouse driver software was
installed prior to running this program.
***** SCAN/CLEAN Version Notes:
The VIRUS TERMINUS(c) V4.6C was built around SCAN/CLEAN 8.9B97
These versions of SCAN/CLEAN incorporate many new options. The
most important option to The Virus Terminus users is the
@filename list file. The Virus Terminus now uses this option
to pass all filename information, options, etc. to SCAN/CLEAN.
The speed of the SCAN/CLEAN FILES function of The Virus Terminus
has increased many times over because of this option. Floppy
users MUST leave the disk containing SCAN, CLEAN, VALIDATE,
VIRLIST, and The Virus Terminus program files in either drive #A
or drive #B (Don't Remove! Unless you are using 360Kb disk swap)
Hard Drive installation users should just use all the same
precautions they have been using .
***** SCAN/CLEAN FILE(s): (Main Menu #1)
Use this main menu selection when all you need to do is
scan or clean an individual or batch of files. The /A ALL
switch is forced on. You may choose file(s) from a paged directory
display if your disk is not write protected. Each time you SCAN or
CLEAN files you are given a choice of what subdirectory to pick
files from.
- PAGE 13 -
You must specify a VIRUS CLEAN CODE before you can 'CLEAN' a
file or batch of files. An attempt to auto-detect the code will be
made if you use SCAN first and provided the Virus ID is still present
on the current screen page when SCAN has finished running. Only the
first ID (looking down from the top of the screen) will be reported
in the case of multiple infections. A manual entry mechanism is also
available for entry of ID codes. Press #2. ENTER VIRUS CODE. The
Virus ID is the character string specified between the [ ]
brackets which SCAN outputs to the screen.
***** SCAN/CLEAN DRIVE(s): (Main Menu #2)
Use this main menu selection when you wish to scan ENTIRE
floppy disks or a hard drive. Turn the /MANY switch on if you
want to SCAN/CLEAN more than one floppy disk.
***** IMMUNIZATION/RECOVERY FUNCTIONS SUBMENU: (Main Menu #3)
(* Advanced User Level! *)
This program feature helps you protect your files/system against
new or unknown virus infectors. Use it wisely.
#1. ADD IMMUNIZATION ( /AG ) : This function will add 52 bytes
of recovery information to each EXE or COM file selected.
The added data facilitates detection and recovery from unknown
or new virus infectors. NOTE: self-modifying files like
MS/PC DOS SETVER.EXE should not have recovery information added
to them. The Virus Terminus will look for a file named
VALNOT.TXT before proceeding. VALNOT.TXT is an ASCII text file
with a list of [path + filename] exceptions not to add recovery
data to. This is a user defined/created file. Read the
documentation that came with SCAN for information on how to
construct such a file. VALNOT.TXT should be placed in The Virus
Terminus directory. You should not add validation data to files
that are already immunized. SCAN with /RG to remove before adding
#2. CHECK IMMUNIZATION ( /CG ) : Performs a SCAN of each file etc.
selected and uses the added recovery data to determine if
selected files, partition table, etc. have been tampered with.
Selecting this function also sends /CERTIFY option to SCAN so
that any files without validation information will be reported.
#3. REMOVE IMMUNIZATION ( /RG ) : Removes the recovery data from
selected files restoring them to original length.
#4. ATTEMPT RECOVERY ( CLEAN /GENERIC ): CLEAN will attempt to
disinfect known/unknown virus infections using the recovery
information added to files and found in SCANVAL.VAL hidden
file(boot record, partition table) and attached to individual
files. Recovery of the original file/area will be attempted.
#5. The CRC CHECKSUM menu selection #5 will perform a two method
check on the file of your choice which will provide a comparison
for future checks. The file display for this selection IS NOT
filtered since you may perform a CRC checksum on ANY FILE.
- PAGE 14 -
** NOTE:
You should not add validation data to files already immunized or to
files that are self-modifying or perform their own self-check!. The
Virus Terminus looks for a USER CREATED ASCII TEXT EXCEPTION LIST
file named VALNOT.TXT . The file must be named VALNOT.TXT, an ASCII
text file, and be located in the same subdirectory as the Virus
Terminus program files. Read the documentation that came with SCAN
for information on how to construct this file. Place this file in the
Virus Terminus directory. Read SCAN95.DOC for more information on
when and when not to add validation.
***** REPORT FUNCTIONS: (Main Menu #4)
Version 4.6C offers several options. The REPORT FUNCTIONS
submenu allows viewing, merging, printing and deleting of report
files. DOS BATCH file execution is also available.
The MERGE function first displays a list of all report files
found in the TERMINUS directory. You may choose from any or all
of them. Then MERGE will create a master file which combines ALL
chosen report files together.
User created custom DOS batch files may be launched by
pressing sub-menu select #3. This version of The VIRUS TERMINUS
allows the user to launch DOS batch files from ANY logical drive
and/or subdirectory. (HARD DISK INSTALLATION ONLY!)
***** SCAN/CLEAN REPORTS:
A report counter is initialized when THE VIRUS TERMINUS is
first run. Each report generated is given a different name by
using the report counter value as part of the name(rpt_1.txt,
rpt_2.txt, etc,) You may generate 35 different reports before
the counter recycles back to #1. It is important to note that the
reports will always start with rpt_1.txt each time the program is
run. Therefore, if you wish to save a report copy it to another
disk or directory so that the original report is not overwritten
the next time that you run THE VIRUS TERMINUS.Version 4.6C allows
report merging as in other versions with one important difference:
As reports are merged into RPTMASTR.TXT they are automatically
deleted so that a separate deletion operation to purge the merged
reports is not necessary anymore.
***** VIRUS FACT SHEETS: (Main Menu #5)
The Virus Terminus, v4.0B, introduced a new main menu
selection : 5. VIRUS FACT SHEETS. Information on individual virus
known characteristics, areas of damage, which McAfee Associates dis-
infector utility to use, etc. is available.
Virus Terminus v4.6C is no longer dependent on CLEAN ID codes.
Users may now browse through the complete list of virus infectors.
Printing of each Fact Sheet is available.
- PAGE 15 -
***** SCAN/CLEAN OPTION SWITCHES
Point the mouse cursor over the word ON! or OFF to change add or
delete options. Press a letter key (A through H) if you are using
the keyboard.
A. SCAN/CLEAN ALL FILE TYPE EXTENSIONS:
SCAN/CLEAN OPTION = /A
SCAN and CLEAN will process ALL files
found instead of just .EXE .COM .BIN

SCAN/CLEAN OPTION: /MAINT
Instructs SCAN/CLEAN to perform partition,
boot record etc. type operations with
considerations for DOS 4.x and higher. NO
files are processed when using this option
& Terminus checks to see if you have DOS
4.0 or higher and will not allow you to
use /MAINT it if not.
G. FAST DISPLAY & SKIP INSIDE LZEXE/PKLITE:
SCAN/CLEAN OPTION: /FAST
Speeds up SCAN / CLEAN operations by not
checking inside LZEXE / PKLITE envelopes.
Display output which shows name of file
being processed is disabled . This option
may cause missing of some virus infections
Read SCAN documentation for more info.

H. TURN ON SCAN/CLEAN REPORT FUNCTION:
SCAN/CLEAN OPTION: /REPORT
Turns on SCAN/CLEAN text file reports. The
report for each run of SCAN / CLEAN is
placed in the TERMINUS directory. The name
of each report is automatically generated
Read VT46CDOC for more info.
***** SAVING SCAN/CLEAN OPTIONS:
To save the state of option switches A .. I simply press
F5-Change Defaults. Then press <ESC> to leave the default
table area. Your option settings are saved along with the other
program parameters found in the default table. Each time you
start Terminus the option settings for switches A .. I will
be restored.
***** OPTIONS LOCK:
OPTIONS LOCK set to the ON position disables the following
options:
MAIN Menu ................... : F3-DOS Shell; F5-Change Defaults;
#6. Run DOS BATCH FILE
SCAN/CLEAN FILE(s) Submenu : SCAN/CLEAN OPTIONS A .. I; F3-DOS SHELL;
F5-Change Defaults;
SCAN/CLEAN DRIVE(s) Submenu : SCAN/CLEAN OPTIONS A .. I; F3-DOS SHELL;
F5-Change Defaults;
IMMUNIZATION/RECOVERY Submenu : F3-DOS Shell; F5-Change Defaults;
#1. ADD IMMUNIZATION; #3. REMOVE
IMMUNIZATION
REPORT FUNCTIONS ............ : F3-DOS Shell; F5-Change Defaults;
#4. DOS BATCH FILE
***** OPTIONS LOCK PASSWORD:
The password supplied as a default is "PASSWORD" . Do not
include the quotes and enter in upper case letters only. The
password default was deliberately left out of the Default Table
to promote operation security. You must edit the file VT46C.CFG
with an ASCII text editor to change the password. VT46C.CFG is
an ASCII text file.
Password is the 18th line in VT46C.CFG . Use ONLY the numbers
0 .. 9 and upper or lower case letters A .. Z . No other keyboard
characters will be recognized. Limit the password to 12 characters
or less. Eliminate any spaces between characters.
- PAGE 17 -
***** LIMIT OPERATION TO SCAN FLOPPIES ONLY: (Start-up option /L)
This mode of operation may be brought up by adding a /L option
at startup and by running TERMINUS from your AUTOEXEC.BAT file.
/L causes Terminus to perform a self-test and then proceed directly
to the SCAN/CLEAN DRIVE(s) submenu setting OPTION LOCK to the ON
position. In addition the drive choices are limited to A: and to B:
if one exists. No exit from this submenu is allowed until the OPTION
LOCK is defeated by pressing F6-OPTIONS LOCK and the correct password
is entered. (Not available with 360Kb disk swapping)
This mode of operation may also be initiated at any time during
normal program operation by moving to the SCAN/CLEAN DRIVE(s)
submenu and pressing F6-OPTIONS LOCK. Upon entering the correct
password the user is given the choice of just locking the normal
amount of options as outlined above or initiating further
limitations to allow SCAN FLOPPIES ONLY.
Password to Continue is required when a virus is detected during
either a SCAN or CLEAN. This will necessitate the intervention of
the Superuser who should take action to prevent further system and
or floppy infection spread. The password required is the same used
to enable/disable the Options Lock. It is strongly suggested that
SCAN/CLEAN OPTION "E - SCAN/CLEAN MULTIPLE FLOPPIES" be left in
the "OFF" position.
The following SCAN/CLEAN DRIVE(s) submenu options are locked and
no access is given to same when in this mode:
1. A .. I SCAN/CLEAN option list
2. F3-DOS SHELL, F5-CHANGE DEFAULTS
3. Submenu selects #2, 3 - Select Virus ID; CLEAN DRIVE
4. Submenu select #4. QUIT - Options Lock must be disabled in order
to leave this submenu when Floppy Lock is ON.
***** USE WITH CAUTION *****
This feature was NOT intended to be used as AN UNATTENDED SCAN
STATION. A SuperUser or System Administrator should be present to
intervene and take control when virus infection is detected.
- PAGE 18 -
Pressing F6 will request the user to enter a password to
disable the lock and return Terminus back to normal operation.
OPTIONS LOCK and FLOPPY LOCK may be toggled ON or OFF by use of
F6-OPTIONS LOCK.
***** EXPERIMENTAL VIRUS DATA:( ADVANCED USER FUNCTION! )
Please read the SCAN docs to get a better understanding
of what an 'experimental virus data file' consists of. If you
decide that you need to utilize this function, press F5-CHG.DEF
and make an entry to the default 'EXP.VIRUS DAT.FILESPEC'. This
entry will be the path and filename for your experimental virus
data file. Next, turn default switch 'EXP. VIRUS DATA ON/OFF' to
the 'ON' position. NOTE: This is the only way to tell THE VIRUS
TERMINUS program to relay the /EXT switch to SCAN. Be sure
to go back to CHANGE DEFAULTS and turn this switch off when you
are finished!
***** WRITE PROTECTED FLOPPY OPERATION:
Running The Virus Terminus, SCAN, CLEAN, etc. from a write
protected floppy is a must if your system is infected. Doing so,
however, imposes a few minor limitations.
A.The SCAN/CLEAN report function will not work since SCAN/CLEAN
must write to the disk to create a report.
B. The SCAN/CLEAN FILES submenu normally uses the @filename
response file for super fast operation. If your floppy is
found to be write protected this mechanism is suspended.
You are not given choice of individual files. Instead, you
must choose from whole subdirectories only.
***** DIRECTORY PATH SELECT:(PATH FINDER)
The PATH FINDER is called up during the following program operations:
1. Default Table entry of program location paths
2. SCAN/CLEAN a file
3. Directory View
4. Immunization/Recovery of files
5. Run DOS Batch File
The Following limitations are imposed:
1. Only paths 64 characters or less are included in the selection
list.
2. A 35 character limition on selected paths is imposed when user
is attempting to grab a path to be placed in the default table.
User is warned and allowed to make another selection.
3. Maximum of 512 paths with manual entry mechanism provided for
monster systems, etc.
- PAGE 19 -
Path Finder will develop a list with a maximum of 512 paths/dirs
starting with the ROOT directories first and working in. This is
usually good enough for most systems. However, some users maintain
massive file/dir inventories. Therefore, a manual entry is provided
for paths/dirs not found on the list. The following are active:
<PGDN> <PGUP> = Display next or previous window page.
<ENTER> = Selects highlighted path.
CTRL-E = Enter a path/dir not on the list.
CTRL-N = Select new drive and path - display new list
CTRL-P = Hardcopy print of the path list with stats.
CTRL-T = Creates an ASCII text file of the path list
in the ROOT directory of the drive that was
scanned.
<ESC> = Quit and return to submenu.
F1,F10 = HELP
***** SCREEN SAVER :
The screen saver is a NON-interrupt driven function which
blanks your computer screen after a pre-determined period of
keyboard or mouse inactivity. The screen saver is turned on
from the Default Table(press F5). Users may enter from 1 to
60 minutes of *approximate* delay time before activation.
The screen saver responds to keypress AND mouse clicks. The
screen saver will not interfere with system I/O's and other
program functions. The following area of Virus Terminus program
operation IGNOREs the screen saver:
1. Any point of keyboard string entry(i.e. Enter Password, etc.)
***** MEMORY AVAILABLE FUNCTION: (LARGEST CONTIGUOUS RAM BLOCK)
Memory available for SHELL launch or VIRUSCAN operations
can be found by pressing CTRL-F key combination while in ANY
MENU or CHANGE DEFAULTS. (This is NOT DISK space, rather computer
RAM memory!)
***** DOS ERRORLEVEL on EXIT:
The Virus Terminus sets the DOS errorlevel upon exit as follows:
0 = Normal Exit 1 = Virus Infection Detected 2 = Abnormal Termination
In the event that a user chooses to (C)ontinue instead of (H)alt when
a virus is detected, the errorlevel will still be set to 1 when the
Virus Terminus is finally quit from the main menu.
- PAGE 20 -
***** OPERATION FROM Microsoft WINDOWS:
The Virus Terminus is a DOS application. It should be run FULL
WINDOW. A "PIF" file is not required although it may be of use to
certain advanced users. A WINDOWS ICON, VTEC.ICO, has been included
with this version of The Virus Terminus.

REMEDY: 1. Press F5-CHANGE DEFAULTS and enter the correct location
of the requested file. Check to make sure that the file
is actually there by doing a directory listing at the
DOS prompt (i.e. DIR C:\UTILITY\VIRUSCAN )
2. Press CTRL-F at the MAIN MENU to determine how much
memory free exists. Memory free reported should be
250Kb or more. Power Down and start over. Check memory
free again. If still not enough, run Virus Terminus
from the DOS prompt instead of your shell, etc.
------------------------------------------------------------------
2. "REPORTS DISABLED WHEN DISK SWAP ON!"
"SELF-TEST DISABLED/DISK SWAP IS ON!"
A /D command line option was detected at program startup.
REMEDY: Use a high capacity installation disk and/or

The CLEAN-up Virus ID Code is not present in the CLEAN-up ID Code
window and you are trying to CLEAN or disinfect a file or diskette.
If SCAN was not previously run and/or Auto-Detect logic couldn't
grab the code from SCAN's output then you MUST press submenu select
#2 Enter Virus ID. The code is displayed by SCAN when a virus
infection is detected. It is the string found BETWEEN the [ and ]
brackets. You may also find a list of codes in the McAfee Associates
file VIRLIST.TXT.
------------------------------------------------------------------
5. "DOS VERSION 4.x OR HIGHER REQUIRED!"
You are trying to use /MAINT and DOS Version 4.0 or higher is
not currently being run or was not used to format the disk
you are working on. (Must be BOOT Drive C:)
