at any time you like in a scanning session.
[Scan] command
scans user-defined drives, directories, and
files for computer viruses or suspicious
files.
[Cure] command
removes viruses from boot sectors and files.
[Statistics] command
displays full statistical data for each drive
tested in the most recent scanning mission.
[Report] command
opens the REPORT file containing the results
of testing or curing of memory, boot sectors,
drives and files. Its name is specified in the
REPORT FILE text box in the panel displayed on
choosing the PATHS... command from the SETUP
menu. This field is operative only if either
the OVERWRITE or APPEND button in the REPORT
FILE field in the OPTIONS panel of the SETUP
is selected.
{}
[Desktop...] field
provides a few options for configuring the
screen display mode to suit user's
preferences.
[Options...] field
provides a few options for configuring the way
in which scanning progress is reported on the
screen.
[Paths...] command
is used to specify the pathnames of files that
are essentional for the normal operation of
Dr. Web program.
{}
The original boot sector is not found in the
"hide-out" where the detected virus must conceal
it. Either this virus is a modified version of
some known virus and hides the boot sector
elsewhere or your computer is infected by a few
boot viruses such that one virus is superimposed
on another. If this is the case, your computer
cannot be booted from such an infected disk.
For help, call the technical maintenance service
of DialogueScience,Inc., Moscow.
{}
This virus does not save the original boot
sector. If you permit Dr. Web to cure the
machine, a standard boot sector will be restored
instead of the original boot sector of your
machine. DO NOT permit Dr. Web to cure your disk
if it is formated by nonconventional disk
administrators like ADM, Disk Manager, SSTOR,
etc., otherwise data on your disk may be lost.
{}
You can suppress this prompt by selecting the
TEST ONE FLOPPY ONLY check box in the panel
displayed on choosing the DESKTOP command from
the SETUP menu.
{}
The file cannot be restored because it is
infected by
(1) an overwriting virus which does not save the
original program code, or
(2) a companion virus, or
(3) a trojan virus, or
(4) the file is damaged beyond repair.
Delete the file and restore it from a backup
copy.
{}
Curing is not possible because your computer is
protected by SHERIFF security system. To clean
the computer, quit Dr. Web, disable SHERIFF, and
then cure your computer.
{}
Dr. Web has detected self-infection. This
happens, as a rule, when Dr. Web is infected by
an hitherto-unknown virus. Close down your
computer and forward a copy of the infected Dr.
Web program to its designer or our authorized
dealer. Soon you will receive a cost-free
database add-on file to kill the virus or the
next upgraded version capable of detecting and
eradicating this virus.
{}
This message warns you that the file had one size
prior to opening and a different size after
opening. Possibly, memory contains an active
resident virus that has infected the file. In
such a case the file size increases. Or there may
be an active stealth virus in the memory that is
trying to hide its copy in the file being tested.
In such a case the file size decreases.
Close down the computer, reboot from a "clean"
bootable diskette and test the suspected files.
{}
Drive not ready! Insert a diskette into drive
and repeat the test or abort testing.
{}
This panel displays full statistical information
about the drives checked in the current scanning
mission.

Additional preferences
----------------------
[X] "Snow" prevention
If snow appears on CGA monitors,
check this item to suppress the glow
of electron beam in its reverse scanning path.
[X] Screen output via BIOS
uses BIOS Int 10h to send the output
to the screen. This mode is very
slow compared to direct access of videomemory
which is the default mode. Check this item if
problems arise in outputing to screen by
direct access of videomemory.

Choosing one of the six option buttons, adjust
color display to suit best your preference:
() Color 1 Default color scheme of Dr. Web
program,
( ) Color 2 This scheme is drawn from Turbo
Vision program,
( ) Color 3 This scheme is drawn from Norton
Utilities,
( ) Color 4 This scheme is drawn from ADinf
program,
( ) Mono 1 Both these schemes display the
message in white
( ) Mono 2 against black background. Choose
the scheme best suited for your
monitor.
Screen height
-------------
Vertical size of screen:
() 25 lines
( ) 30 lines
( ) 45 lines
{}
Main settings
-------------
are the main configuration parameters
controlling the operation of Dr. Web.
[X] Memory test
tells Dr.Web to verify the memory at
the start of each scanning session.
The memory range to be tested is selected
in this panel in the MEMORY RANGE field.
Memory range
------------
( ) 640 - conventional memory
() 1088 - conventional memory, UMB, and HMA.
[X] Boot sector test
tells Dr.Web to scan the master boot
record and boot sectors of drives.
[X] Heuristic analysis
tells Dr.Web to check files and boot
sectors of drives for new and
unknown viruses. In this mode Dr. Web will
verify whether a program is an executable file
or a virus code. The heuristic analysis level
is specified in this panel.
Heuristic level
---------------
must be such that no false alarms are
triggered. The higher the heuristic level, the
higher the percentage of errors or false
alarms. The following is a list of
experimental data on the determination of
different viruses in 10000 infected files:
() Minimal - about 87%,
( ) "Paranoid" - about 89-91%.
Minimal level is equally adequate for
heuristic analysis of new files.
[X] Check for TSR-virus
tells Dr. Web to check the changes
taking places in the size of a file
being tested at the time of opening and/or
searching for files. Many resident viruses try
to infect files at the time of opening or
writing. Stealth viruses additionally hide
their presence when an infected file is
opened.
Files
-----
field contains four check boxes to tell Dr.
Web to verify packed files, achives and to
cure infected files. The CURE check box is
operative only when the CURE command is chosen
from the TEST menu or when its speedkey
Ctrl-F5 is pressed.
[X] Check packed
When this box is selected, packed
files will be exploded in a
temporary directory prior to testing. For this
purpose you must specify a drive for creating
a temporary directory in the TEMP DRIVE text
box in the panel displayed on choosing the
PATHS... command from the TEST menu.
[X] Check archives
To check the files inside an archive
file created with ARJ, PKZIP, RAR,
LHA, ZOO, ICE and HA.
[X] Delete damaged
When this box is selected, Dr. Web
will delete those infected files
that do not yield to restoration and the files
that are damaged by viruses beyond repair.
[X] Prompt for cure
When this box is selected, Dr. Web
will ascertain your intention prior
to curing an infected file. When this box is
deselected, Dr. Web will automatically remove
virus codes from infected files.
Infected files defines a method for
-------------------- removing viruses when
cure command is selected.
() Cure Deletes the virus codes
from infected files.
( ) Delete Deletes infected files
from the drive.
( ) Rename Renames infected files by
substituting "V" for the
first letter in the
filename extension. Files of extensions COM, EXE
are renamed with the default name but with
extensions VOM and VXE, respectively.
Report file will create a file for
----------- writting the results of every
scanning mission.
() Don't create Report file is not created.
( ) Overwrite The results of every scanning
mission will be overwritten
in the report file.
( ) Append The results of every scanning
mission will be appended at
the end of the existing
report file.
The name of the report file is to be specified in
the menu box [Setup]|[Paths]|[Report file name].
If the full pathname of the report file is
entered in this box, the results of a scanning
mission can be viewed through the command [Test]|
[Report].
{}
Add-on files
------------
This panel is used for searching and appending
add-on update files to the main virus
database. In the text box, type a name or
search pattern for finding and appending
add-on files. Upon successful updating, a
message to this effect and the number of
add-on files appended to the main virus
database are displayed.
{}
Add-on search pattern
---------------------
In the text box, you can type a search pattern
for finding add-on update files to the main
virus database. Upon executing the APPEND
command in the ADD-ON FILES panel displayed on
choosing the UPDATE command from the main
menu, Dr. Web will find files matching the
search pattern entered in this text box. If an
add-on file is found, it is automatically
appended to the main virus database.
Add-on update files are released approximately
once every week. Registered users can obtain
them free of cost from our authorized dealers.
Add-on pathname
---------------
In this text box, you can type and edit a
pathname for finding add-on update files.
Temp drive
----------
In the text box, type the name letter of the
drive where Dr. Web can create a temporary
directory for exploding and testing packed
files. The TEMP DRIVE must be READ/WRITE and
have enough free space (about 500-1000 Kb) for
storing temporary files. If there is a RAM
drive of sufficient space in your machine, it
is a good idea to specify it as a TEMP DRIVE
as this will speed up the work.
Report file name
----------------
In the text box under this item, type the full
pathname where you want Dr. Web to create a
REPORT FILE for writing the results of
scanning sessions.
File type
---------
field contains three option boxes for choosing
the type of files to be tested:
( ) All files files of any extension,
() Programs executable files (COM, EXE,SYS,
BAT, DRV, BIN, DLL, BOO, OV?,
DOC, and DOT files).
( ) User-defined
└ *.COM *.EXE In the text box under this
field you an enter and edit
the type of files and their
filename extension. Only files of the type
specified in this text box will be tested
and cured in scanning sessions, unless you
type a different file specification in the
panel displayed on choosing the SCAN command
from the TEST menu. For example, if the user-
defined files field specifies COM and EXE
files but you specify BIN files in the SCAN
command panel, then Dr. Web will verify only
BIN files and ignore COM and EXE files in the
current session.
{}
In the text field of the SCAN PATH panel, type
the name of a drive, directory, subdirectory or
file for testing and curing. The pathname can be
specified, using global file characters; e.g.,
C:, C:\DOS, C:\DOS\*, C:\DOS\FILE.*, C:\DOS\*.*,
... If several paths are specified concurrently,
they must be separated by intervening spaces, for
example, C: D:\FILE.EXE E:\UTIL\UNKNOWN\*.COM.
The global characters * and *: denote that all
logical drives in the hard disk must be scanned.
{}
Insufficient space in TEMP DRIVE for exploding
this packed file. Specify a different drive
having sufficient free space for creating a
temporary directory in the text box under TEMP
DRIVE in the panel displayed on choosing the
PATHS... command from the SETUP menu. Otherwise
the whole or a part of the file will be skipped
in scanning.
{}
This file or the boot sector of the drive is
infected. Unless you permit Dr. Web to cure the
situation, the consequences will be unpredictable
and disastrous.
{}
The add-on file successfully appended to the main
virus database. The number viruses which Dr. Web
can now detect and eradicate has been increased
by the figure shown in the message box.
{}
The information from this add-on file was already
appended to the main virus database.
{}
You have typed options that are not valid for the
Dr. Web command line. Type the command options
properly and run Dr. Web once again.
{}
Memory seems to contain an active TSR virus.
Reboot the computer from a "clean" bootable
diskette containing the Dr. Web program and test
the memory and all drives in your system.
{}
