INTRODUCTION
Virus Central is a shell program that simplifies the use of
VirusScan and CleanUp, both from McAfee Associates. It provides
a menu oriented environment that does away with the need to
memorize command line parameters. It is ideally suited for
locations that devote a computer to checking incoming diskettes
for virus infections (i.e. the computer lab of a college). The
user interface is graphical and works well with a mouse,
although keyboard use is equally pleasant. As an added bonus,
Virus Central has a built-in screen-saver that clears the screen
after a specified amount of time to prevent screen image
burn-in.
The single most powerful feature of Virus Central is its Clean
Up sequence. As a disk is scanned using VirusScan, infections
detected are noted and placed in a queue. After the scan is
completed, Virus Central executes CleanUp and passes the
information stored in the queue to the program, effectively
automating the process. This feature is invaluable for cleaning
disks with multiple file infections.
This manual has been prepared to familiarize you with Virus
Central. Although already fairly easy to use, I suggest you take
some time to go over this text to learn more about the program.
I have tried to be as thorough as possible in order for users to
fully benefit from Virus Central. A special note should be made
that the samples of the menus in the text are not exact replicas
of the menus that you will see on the screen; I had to make do
with what was available from the text character set.
I would like to express my gratitude to Mr. John McAfee, who
reviewed and tested a preliminary copy of the program, and whose
kind words convinced me of its potential. And all the guys 'n
gals in the College of San Mateo's computer lab (Charlotte,
Mike, John, Mark, Dave, Tonette, Robin, Stan, Steve, Yulin, and
Andy), for pushing the project to a higher ground.
THANK YOU, All!

SYSTEM REQUIREMENTS:
To get the most from Virus Central, your system should have the
following:
* 384k RAM (MINIMUM) - This is a theoretical minimum, although
I have only tested Virus Central on machines with 512k and
greater.
* MS-DOS/PC-DOS 2.1 or later.
* A hard disk drive - it may be possible to run Virus Central
off of two floppy disk drives or even a RAM drive, but it
was intended to run off of a hard disk.
* A CGA compatible video adapter/display - Virus Central uses
the 640 x 200 pixel, 2 color graphics mode, requiring a CGA
compatible machine (most EGA and VGA cards are compatible).
* A mouse (optional).
INSTALLATION
Virus Central requires 2 program files to operate, along with
VirusScan and CleanUp. The files are:
CENTRAL.EXE - The main Virus Central program
CENTRAL.CFG - The configuration file for Virus Central
To install, simply copy these two files to the same directory on
your hard disk as VirusScan and CleanUp. Make sure that you have
set the DOS "PATH" variable to that directory, so that you may
execute the program from any other directory. Virus Central
(or, simply, "Central") normally searches the path for the
configuration file.
The distribution copy of Central is configured for a machine
that has three disk drives (A, B, and C), drives A and B
designated as the "Quick-Key" disk drives, the VirusScan and
CleanUp programs installed in the root directory of the hard
disk ("C:\"), the Stoned / Marijuana virus specified as the
default virus, and the list of viruses recognized by CleanUp 64.
If you wish to make changes to this configuration, refer to the
"Set Up Menu" discussion later in this text.
Page 2
USING VIRUS CENTRAL
To use Virus Central, simply enter "CENTRAL" at the DOS prompt.
Central normally looks for a mouse driver, and, if a driver is
installed, initializes the program's mouse handling routines. If
your mouse driver is installed and you prefer to use Central
without the mouse, enter "CENTRAL /NOMOUSE" instead.
Screen Lay Out
Assuming everything works alright, Central's user screen will
appear. The main menu, located on the top row of the screen,
presents you with 5 options:
Virus Scan : allows you to modify the options of VirusScan
and execute the program
Clean Up : allows you to modify the options of CleanUp and
execute the program
Set Up : allows you to modify the configuration of Virus
Central and save them to disk
DOS Shell : loads up a copy of the DOS command processor
Quit : terminates Virus Central and returns to DOS
Aside from the above mentioned options, there is a small diamond
character on the upper-left corner of the screen, used for
manually invoking the screen-saver with a mouse.
On the lower-right portion of the screen are four boxes,
indicating the "Quick-Key" options; function keys [F1] to [F4]
assigned to scan/clean user selected disk drives. On the
upper-right portion of the screen is a small box containing the
ID of the current virus (by default, this is "[STONED]"). This
tells you which virus a Quick-Key clean will remove.
On the lower-left, occupying a majority of the user's screen, is
the VirusScan/CleanUp window, which I affectionately refer to as
the "black box." Output from VirusScan and CleanUp, which
normally goes to the text screen, is diverted to this window, so
that you never have to leave the Central user's screen. This
window has a text resolution of 80 x 22 characters; three lines
had to be sacrificed to make the black box fit right on the
screen, but this affects VirusScan and CleanUp minimally.
================================================================
IMPORTANT!
Because the main menu options "Virus Scan" and "Clean Up" are
directly related to the "VirusScan" and "CleanUp" programs,
respectively, it will be the notation of this manual to refer to
Page 3
"Virus Scan" and "Clean Up" (with spaces between the words) as
the program options of Virus Central, and "VirusScan" and
"CleanUp" (without spaces between the words) as the actual
programs of McAfee Associates; the executable files "SCAN.EXE"
and "CLEAN.EXE"
================================================================
General Notes On Mouse Use
Most of the options in Virus Central are mouse selectable. To
select an option with a mouse, position the mouse cursor (a
black arrow) over the desired option and press any key on the
mouse. This mouse selection process of positioning and pressing
will, from here on, be refered to as "clicking," and any phrase
that goes "click on..." or "clicking on..." will refer to this
procedure.
Some options, such as the Quick-Keys on the user's screen, are
enclosed in little boxes. These options are mouse selectable by
clicking anywhere inside the box.
When entering a string, such as the overlay extension list in
the Virus Scan menu, or a number, such as the color setting in
the Program sub-menu, a mouse may be used to select the option,
but cannot be used to position the cursor for editting or
entering the string/number.
Options From The Main Menu And User's Screen
Options are easily selected using the keyboard or a mouse (if
one is available). When an option is available, it is shown on
the screen as bold characters. When an option is not available,
it is "fuzzed" out, and attempts to select it will fail.
There are three ways to select options from the main menu. You
could use the left and right arrow keys to move the cursor over
the desired option and press [Enter] to select it. A quicker way
is to press the letter key corresponding to the underlined
letter of the option (i.e. press [V] to select the Virus Scan
option). The third method would be to click on it with the
mouse. Note that the Virus Scan, Clean Up, and Set Up options
produce their own menus, and even sub-menus.
Function keys [F1] to [F4] are defined as Quick-Keys; [F1] and
[F2] execute the VirusScan program, and [F3] and [F4] execute
the CleanUp program. The parameters passed to the VirusScan and
CleanUp programs are those set from the Virus Scan, Clean Up, or
St Up menus. By default, disk drives A and B are designated as
Quick-Key disk drives, where:
[F1] executes VirusScan on the default directory of drive A,
[F2] executes VirusScan on the default directory of drive B,
Page 4
[F3] executes CleanUp on the default directory of Drive A, and
[F4] executes CleanUp on the default directory of drive B.
The Quick-Key disk drive assignments may be changed from the
Set Up menu's Program sub-menu. It is advisable to designate
floppy disk drives as Quick-Key since floppy disks are the ones
most often checked for infections.
One of Virus Central's most attractive features is its built-in
screen-saver. The screen-saver prevents Central's graphics
screen from "burning into" your monitor by blanking your screen
and displaying psychedelic, seemingly random graphics. Pressing
any key or mouse button returns you to the program, at the point
you left off. Normally, the screen-saver is automatically
triggered by Central after a set number of minutes of "idle
time" (3 minutes, by default). For our purposes, idle time is
defined as a period wherein Central awaits keyboard or mouse
input and is not executing any other task. From the user's
screen, you can manually invoke the screen-saver by pressing the
[B] key or by clicking on the diamond character on the
upper-left corner of the screen. The number of minutes of idle
time Central waits, the "time lapse," may be set from the Set Up
menu's Program sub-menu.
Page 5
THE VIRUS SCAN MENU
Selecting the Virus Scan option from the main menu pops the
Virus Scan menu. This menu allows you to set the parameters of
the VirusScan program and execute it. Although you can execute
VirusScan using the Quick-Keys, this menu allows you to scan a
drive not designated as a Quick-Key drive.
The Virus Scan menu has 10 fields that affect the execution of
VirusScan and only two options; "Okay," which accepts any
changes made and executes VirusScan, and "Cancel," which cancels
any changes made and returns to the main menu. It looks
something like this:
┌────────────────────────────────────────────┬───────────┐
│Disk Drive....................... : [-A-] │F10: Okay │
│Skip inside scan of LZEXE files.. : NO ├───────────┤
│Overwrite & delete infected files : NO │Esc: Cancel│
│Scan memory for all viruses...... : NO └───────────┤
│Scan all files................... : NO │
│Scan listed overlays............. : NO │
│Skip memory scan................. : NO │
│Scan multiple floppies........... : NO │
│Attempt automatic Clean Up....... : NO │
│Overlay extension list........... : .OVL .OVG .OV1 .OV2 │
│File path to scan................ : │
└────────────────────────────────────────────────────────┘
All of these fields, with the exception of "Attempt automatic
Clean Up," correspond to the command line parameters of the
VirusScan program. To select a field, use the up and down arrow
keys to position the cursor and press [Enter] to select it. You
may also click on a field with the mouse to select it.
The first field specifies the disk drive to scan. When this
field is selected, you will be presented with a string of
letters, indicating the available disk drives. Select a disk
drive from the list by using the left and right arrow keys to
position the cursor over the letter of the disk drive you wish
to scan and press [Enter] (i.e. position the cursor over "B" if
you wish to scan drive B:). A simpler way would be to press the
letter key corresponding to the desired drive (i.e. press [B] to
scan drive B:). Note that the string displayed on the screen is
only five characters wide. The list of available disk drives may
actually be longer; use the left and right arrow keys to scroll
through the available disk drives. Central does not allow you to
specify more than one drive letter at a time, although VirusScan
can handle it.
The next seven fields "toggle" the parameter options; you
either want them when VirusScan executes (YES) or you do not
want them (NO). When you position the cursor over these fields
and press [Enter], or click on them with the mouse, the setting
of the fields change from "NO" to "YES," and from "YES" to "NO."
Page 6
The first six of these fields correspond to the VirusScan
command line parameters as follows:
Skip inside scan of LZEXE files -> /NLZ
Overwrite & delete infected files -> /D
Scan memory for all viruses -> /M
Scan all files -> /A
Scan listed overlays -> /E
Skip memory scan -> /NOMEM
Scan multiple floppies -> /MANY
The last toggle field, "Attempt automatic Clean Up," specifies
whether or not Central will execute the Clean Up sequence right
after the scan is completed, without prompting you to begin the
sequence. Regardless of the setting here, Central will maintain
a queue of detected infections.
The next field is the overlay extension list. This is a string
specifying the extensions of overlay files that scan will
examine if the "/E" parameter is specified. The extensions
should begin with a period, followed by the three character
extension, and separated by spaces (i.e. ".OVR .OVG .OVL").
The maximum length of this string is 40 characters.
The last field in the menu sets the file path that VirusScan
will check. This is normally blank, in which case the entire
disk is checked. But if you wish to localize the scan to a
single directory, or even a single file, set this string to the
file path you wish to scan. Do not specify the drive, since it
is already specified in the first field of this menu.
Once you have all the parameters set, select the "Okay" option
by pressing [F10] (or clicking on the "Okay" box) and Central
will execute VirusScan with the set data. Note that the changes
made to the fields will become the current settings and will
remain active.
If you change your mind and decide that you do not wish to
execute VirusScan, select the "Cancel" option by pressing [Esc]
(or clicking on the "Cancel" box) and Central will return to the
main menu. Any changes made to the fields in the Virus Scan menu
will be lost; all settings reverting to their previous states.
Page 7
THE CLEAN UP MENU
Selecting the Clean Up option from the main menu pops the Clean
Up menu. This menu allows you to set the parameters of the Clean
Up program and execute it. Although you can execute CleanUp
using the Quick-Keys, this menu allows you to clean a drive not
designated as a Quick-Key drive.
The Clean Up menu has five fields that affect the execution of
CleanUp and only two options; "Okay," which accepts any
changes made and executes CleanUp, and "Cancel," which cancels
any changes made and returns to the main menu. It looks
something like this:
┌──────────────────────────────────┬───────────┐
│Disk Drive............. : [-A-] │F10: Okay │
│Check all files........ : NO │Esc: Cancel│
│Clean multiple floppies : NO └───────────┤
│Virus Name............. : Stoned / Marijuana │
│File path to clean..... : │
└──────────────────────────────────────────────┘
All of these fields correspond to the command line parameters of
the CleanUp program. To select a field, use the up and down
arrow keys to position the cursor and press [Enter] to select
it. You may also click on a field with the mouse to select it.
The first field specifies the disk drive to clean. When this
field is selected, you will be presented with a string of
letters, indicating the available disk drives. Select a disk
drive from the list by using the left and right arrow keys to
position the cursor over the letter of the disk drive you wish
to clean and press [Enter] (i.e. position the cursor over "B" if
you wish to clean drive B:). A simpler way would be to press the
letter key corresponding to the desired drive (i.e. press [B] to
clean drive B:). Note that the string displayed on the screen is
only five characters wide. The list of available disk drives may
actually be longer; use the left and right arrow keys to scroll
through the available disk drives. Central does not allow you to
specify more than one drive letter at a time, although CleanUp
can handle it.
The next two fields "toggle" the parameter options; you either
want them when CleanUp executes (YES) or you do not want them
(NO). When you position the cursor over these fields and press
[Enter], or click on them with the mouse, the setting of the
fields change from "NO" to "YES," and from "YES" to "NO."
These two fields correspond to the CleanUp command line
parameters as follows:
Clean all files -> /A
Clean multiple floppies -> /MANY
Page 8
The next field is the name of the virus CleanUp will remove from
the disk. Selecting this field pops a sub-menu, displaying a
list of virus names from which you can select. Use the up and
down arrow keys to position the cursor over the desired virus
name and press [Enter]. You may also select a virus name by
clicking on it with the mouse (click on the up and down arrows
on the menu to scroll through the list). When you have selected
a virus name, select the "Okay" option from the sub-menu, either
by pressing [F10] or clicking on the "Okay" box, to make CleanUp
remove this virus. If you change your mind, select the "Cancel"
option from the sub-menu, either by pressing [Esc] or clicking
on the "Cancel" box, and the virus name selected will be
ignored. In either case, you will return to the Clean Up menu.
The last field in the menu sets the file path that CleanUp will
clean. This is normally blank, in which case the entire disk is
checked for the infection. But if you wish to localize the
process to a single directory, or even a single file, set this
string to the file path you wish to clean. Do not specify the
drive, since it is already specified in the first field of this
menu.
Once you have all the parameters set, select the "Okay" option
by pressing [F10] (or clicking on the "Okay" box) and Central
will execute CleanUp with the set data. Note that the changes
made to the fields will become the current settings and will
remain active.
If you change your mind and decide that you do not wish to
execute CleanUp, select the "Cancel" option by pressing [Esc]
(or clicking on the "Cancel" box) and Central will return to the
main menu. Any changes made to the fields in the Clean Up menu
will be lost; all settings reverting to their previous states.
Page 9
THE SET UP MENU
The Set Up option from the main menu pops the Set Up menu. From
here you can configure Virus Central to your computer and set
the default parameters for VirusScan and CleanUp. If your
computer does not conform to the default set up, this should be
the first option from the main menu that you select before
anything else.
There are five options in this menu, the first four of which pop
individual sub-menus. To select an option from this menu, use
the up and down arrow keys to move the cursor over the desired
option and press [Enter]. Alternatively, you can click on an
option with the mouse. When you are done making changes, you can
return to the main menu by pressing [Esc], or clicking anywhere
outside the menu borders.
THE PROGRAM SUB-MENU
The Program sub-menu configures Virus Central to your computer.
If your machine is configured differently from the default
settings, be sure to make the necessary changes in this menu.
The Program sub-menu has five fields that affect the execution
of Virus Central and only two options; "Okay," which accepts any
changes made, and "Cancel," which cancels any changes made.
Either option returns you to the Set Up menu.
The program sub-menu looks something like this:
┌───────────────────────────────────────────────────────────┐
│Virus Scan / Clean Up directory path : C:\ │
│Disk drive list..................... : ABC │
│Quick-key Scan / Clean disk drives.. : AB ┌───────────┤
│Color setting....................... : 16 │F10: Okay │
│Screen saver time lapse (minutes)... : 3 │Esc: Cancel│
└───────────────────────────────────────────────┴───────────┘
To select a field, use the up and down arrow keys to position
the cursor. You may also click on a field with the mouse to
select it. Unlike the fields in the Virus Scan and Clean Up
menus, the fields in this sub-menu are all similar; they all
contain editable data. For this reason, you do not have to press
[Enter] to begin editing/entering data. In this sub-menu, the
cursor is always in an "edit ready" position.
The first field specifys the directory path to the VirusScan and
CleanUp programs. For example, if these programs are in a
directory called "VIRUS" in the C: drive, this field should be
set to "C:\VIRUS\" When Central first executes, it checks this
specified directory for the two programs. If it cannot find them
there, it will search the other directories in the DOS PATH,
which can take a little longer. It is a good idea to have the
Page 10
VirusScan, CleanUp, and Virus Central programs all in the same
directory, to make it easier for Central to locate the necessary
program files.
The next field is the disk drive list. This is a string that
specifys the drive letters of all physical disk drives on your
machine. For example, if your machine has four disk drives,
labeled A:, B:, C:, and D:, the disk drive list should be "ABCD"
This string can contain the capital letters "A" to "Z." Bear in
mind that you should only specify "physical" disk drives. Do not
specify network disk drives and RAM drives.
The third field is the Quick-Key disk drive list. This is a two
character string specifying which of the available disk drives
will be assigned as Quick-Key disk drives. Choose any two from
the disk drive list. If this field is blank, then no disk drive
is assigned as a Quick-Key drive. If only one disk drive is
specified, then only that drive is assigned as a Quick-Key
drive.
The next field sets the color of the display. This is a number
from 0 and 16. On true CGA systems, the color setting affects
the foreground color and leaves the background color always
black. On most EGA and VGA systems, however, changing the color
setting has funny results; the background and foreground colors
change in, mostly, funny combinations. Normally, you are only
allowed to use values from 0 to 15, but color setting 16 was
provided to force a white-on-black screen.
The last field sets the screen saver time lapse. This is the
number of minutes of idle time Central waits before invoking the
screen-saver. This is a number between 1 to 60. A safe setting
is about three minutes.
THE VIRUS SCAN SUB-MENU
The Virus Scan sub-menu allows you to set the parameters for the
Virus Scan option from the main menu. This sub-menu is the same
as the Virus Scan menu, except that the "Disk drive" and "File
path to scan" fields are disabled, and you cannot execute
VirusScan from here. Refer to the "Virus Scan Menu" section on
using this sub-menu. Selecting the "Okay" option accepts all
changes made to the fields and makes them current, while
selecting "Cancel" restores the fields to their previous
settings. In either case, you will return to the Set Up menu.
THE CLEAN UP SUB-MENU
The Clean Up sub-menu allows you to set the parameters for the
Clean Up option from the main menu. This sub-menu is the same as
the Clean Up menu, except that the "Disk drive" and "File path
to clean" fields are disabled, and you cannot execute CleanUp
Page 11
from here. Refer to the "Clean Up Menu" section on using this
sub-menu. Selecting the "Okay" option accepts all changes made
to the fields and makes them current, while selecting "Cancel"
restores the fields to their previous settings. In either case,
you will return to the Set Up menu.
THE VIRUS LIST SUB-MENU
The Virus List sub-menu is a maintenance feature for updating
and modifying the virus list used by the Clean Up menu. You can
add, edit, or remove virus names and IDs from the list. It is a
good idea to use this feature whenever new versions of the
VirusScan and CleanUp programs are released, keeping the virus
list up to date. The virus list can contain up to 300 virus
names and IDs. Also, Central requires the first twenty virus
names and IDs as the bare minimum, so you will not be able to
edit or remove the first twenty viruses on the list.
The Virus List sub-menu is the same one used in the Clean Up
menu, except that it has three more options for adding, editing,
and removing viruses from the list. It looks something like
this:
┌──────────────────────────────┬─┬───────────┐
│Ashar ├─┤ │
│Disk Killer │ │F1 : Add │
│1701 / Cascade │ │F2 : Edit │
│Stoned / Marijuana │ │F3 : Remove│
│Ping Pong-B / Cascade Boot │ │F10: Okay │
│Ping Pong / Bouncing Dot │ │Esc: Cancel│
│Jerusalem-B ├─┤ │
└──────────────────────────────┴─┴───────────┘
To add a virus to the list, select the "Add" option (by pressing
[F1] or clicking on the "Add" box) and you will be prompted to
enter a new virus name and ID. When they are entered, select the
"Okay" option (by pressing [F10] or clicking on the "Okay" box)
to add the virus name and ID to the virus list. If you change
your mind and decide that you do not want to add it to the list,
select "Cancel" (by pressing [Esc] or clicking on the "Cancel"
option). In either case, you will return to the Virus List
sub-menu.
To edit a virus name and/or ID on the list, use the up and down
arrow keys to position the cursor over the name of the virus on
the list (or click on it), then select the "Edit" option (by
pressing [F2] or clicking on the "Edit" box). You will be
prompted to edit the virus name and ID. When done, select the
"Okay" option to update the virus name and ID. If you change
your mind and decide that you do not want the name and ID
changed, select "Cancel." In either case, you will return to the
Virus List sub-menu.
Page 12
To remove a virus name and ID from the list, use the up and down
arrow keys to position the cursor over the name of the virus on
the list (or click on it), then select the "Remove" option (by
pressing [F3] or clicking on the "Remove" box). Select the
"Okay" option to remove the virus from the list. If you change
your mind, select the "Cancel" option. In either case, you will
return to the Virus List sub-menu.
When all changes are made, select "Okay" to make the changes to
the virus list current. Selecting "Cancel" restores the virus
list to its previous state. In either case, you will return to
the Set Up menu.
SAVE OPTIONS
Selecting "Save Options" from the Set Up menu writes the current
settings of Virus Central to the CENTRAL.CFG file, and these
changes will also be in effect the next time you execute
Central. If you have modified any of Central's settings and you
do not save them using this option, you will be warned and given
the opportunity to save them when you select the Quit option
from the main menu.

THE DOS SHELL OPTION
The DOS Shell option from the main menu loads up the DOS command
processor. This returns you to the text screen where you may
issue DOS commands and even run other programs. Virus Central
remains resident in memory and, as such, limits the amount of
memory available to you in the DOS shell. This feature is
particularly useful if you ever need to run VirusScan or CleanUp
manually. To return to Central, enter "EXIT."
THE QUIT OPTION
The Quit option terminates Virus Central and returns you to DOS.
If Central's configuration has changed and they are not yet
saved, you will be warned and given the opportunity to save the
changes.

THE CLEAN UP SEQUENCE
Virus Central's most most powerful feature is the Clean Up
sequence. As a disk is scanned using VirusScan, infections
detected are noted and placed in a queue. After the scan is
completed, Central executes CleanUp and passes the information
stored in the queue to the program, effectively automating the
process. This feature is invaluable for cleaning disks with
multiple file infections.
The queueing process is, for all intents and purposes,
automatic; Central will always enqueue infections detected by
VirusScan. There are points, though, that you should be aware of
about the feature:
* The queue can hold up to 300 individual infections. If there
are more than 300 on the disk (that is one messed up disk!),
VirusScan will continue to scan, but Central will ignore those
passed the limit.
* Central will always enqueue detected infections, even if
VirusScan is executed with the "overwrite & delete infected
files" option.
* The Clean Up sequence works on individual files; that is, it
executes CleanUp on each file where a virus was detected, even
if the same virus was discovered on more than one file.
* The Clean Up sequence executes CleanUp without the "check al
files" and "clean multiple disks" options, even if they are
set from the Clean Up menu. Also, the memory scan is disabled.
* If VirusScan detects infections, and the "attempt automatic
clean up" option is off, you are asked if you wish to initiate
the Clean Up sequence. If you decide not to, the queue is not
cleared. It will prompt you, again, if you wish to initiate
the sequence when you attempt to scan or clean another disk.
* The Clean Up sequence may be interrupted by pressing [Ctrl-C].
