1. Using Virus Buster Lite
==========================
1.1 Starting
------------
Virus Buster Lite is a virus signature scanner. See the section on
Virus Buster for information on other types of anti-virus tools.
Virus Buster Lite is designed to be fast and positive.
Use it if you want a good fast signature scan for known viruses.
1.2 Installing
--------------
Basically, just copy the files to a convenient location and then
run the program.
If you are installing the registered version, the first time you
run it, it asks for a registration name. This name will be displayed
at the bottom of the screen and "brands" the program as yours.
You only need to enter the name once, Lite will remember it.
You could use Virus Buster Lite in a number of ways, here are two.
+ As a daily scan across a hard disk
Copy all files to new directory on your hard disk
and add a command line to your AUTOEXEC.BAT.
+ As a scanner on a utility diskette
Copy all files to a freshly formatted system diskette.
To check a machine, boot from the floppy and then run
the program.
1.3 Command line switches
-------------------------
Virus Buster Lite is made to run as fast as possible, so the
main program is simply called "V".
This is the format of the command line:
V [drive:directories_to_scan...] [options] <Enter>
If you run V without any switches it will scan the current directory
and any subdirectories for files and then terminate. If an infection
is detected it will ask you what you want to do about it.
To get it to check another disk or directory, just specify it after
the "V". If you ask it to scan a floppy it will automatically repeat
the scan as you insert new diskettes.
To scan multiple drives or directories, just specify them one after the
other on the command line, with spaces between.
E.G. "v c d e" will scan all drives C:,D: and E:
"v c:\dos c:\windows" will scan directories DOS & WINDOWS on C:
If you want it to do more than that here are the switches you can use.
Option switches are in format "[[/O[+|-]][..]....]". So if you add a
"+" after the switch it means turn it on, a "-" means turn it off.
Options can be given in any order. Separation spaces are unnecessary.
/A (default is ON)
Automatically repeat scan for floppy diskettes. (You don't need to
press a key to continue).
/B (default is off)
Use sound effects with the Sound Blaster SBTALKER driver loaded
or the SPKDRV driver loaded. (see section 1.4).
/C (default is off)
Continuous scanning, if infections are found they are logged but
you are not prompted to delete the infected files.
/D (default is off)
Delete all files found to be infected, without confirmation.
/F (default is off)
Send a full report to the log file. Clean files are noted as
well as infections.
/H (default is off)
Run in hidden mode, with no screen display. Use this with the
/S or /P switch to protect a machine without users knowing
about it.
/Jppp (default is use current directory)
You can use this switch to specify where Lite's data files are.
Normally these are located in the same directory as V.EXE and
Lite will find them if they are there. But you might, for example,
want to keep the data files in a safe area of a network drive.
E.G. "v /jf:\secure\data\virusinf"
/L (default is ON)
Log infections to file V.LOG
/R (default is ON)
Do recursive scan into all subdirectories.
/S (default is off)
Stop scanning (hang the PC) if any infection is found.
/Tppp (default is use current directory)
You can use this switch to specify where Lite's log file goes to.
Normally this is written to the same directory as V.EXE. But you
might, for example, want to log the results to a network drive.
E.G. "v /tf:\audit\virusinf\user23"
/Nnnn (default is off)
Stop scanning if no infection is found after "nnn" files have
been scanned.
/O Only scan the MBR, boot record and memory (no files).
/Pppp (default is off)
If an is infection found, hang until the user enters password "ppp".
/8 On early revisions of the 80386 chip, there is an intermittent
bug which causes divide by zero errors.
If you have an old 386 and you get occasional crashes with an
error "200", use the /8 switch to force Lite into 286 mode.
(For techos, the CDQ instruction sometimes fails to clear the
upper word of EDX, leading to an overflow when doing a division.
Apart from checking each time to see if it has cleared <too slow>,
the only possible workaround is to avoid use of doubleword DIV.)
1.4 Sound Effects
-----------------
Virus Buster Lite supports the use of a Sound Blaster card, or it
can use the PC speaker to give similar (but lower quality) sound
effects.
The use of sound effects has been made an optional extra as it
will use another 20 to 50K of memory, depending on the driver
used.
To use Virus Buster Lite with sound effects, the appropriate
driver needs to be loaded. You can simply run VB.EXE instead
of V.EXE and the driver will be located, loaded and unloaded
for you.
You use the same command line switches for VB as for V.
If you normally have the Sound Blaster driver SBTALKER loaded,
you don't need to run VB.EXE (although doing so should still work
fine). You can instead just run V.EXE and add a "/B" to the command
line.
Note: If you have a Sound Blaster but VB doesn't use it check the
following:
In your AUTOEXEC.BAT you should have a line like:
SET SOUND=C:\SB
This points VB to the sound blaster directory. VB expects that
there will be a subdirectory C:\SB\SBTALKER containing the files
SBTALKER.EXE and BLASTER.DRV.
If you have installed the SBTALKER into a different directory
you should add the following line to your AUTOEXEC.BAT:
SET TALKER=d:\your_directory
If all else fails, you can load SBTALKER manually and then run V /B.
1.5 Error messages
------------------
If something goes wrong you should get an error message. The DOS
errorlevel will also be set to >0 and can be trapped. The following
are the most common errors.
Checksum error in file
The program self check has failed. The scanner may be itself
infected or is damaged in some way and so scanning is aborted.
Obtain a fresh copy of the program from a reliable source.
Requires DOS 2.0 or above
The program will not operate on DOS 1.x, you need to upgrade
to a real version of DOS.
Cannot allocate memory
There is not enough memory to run the scanner. Try to allow
the program more memory by unloading some TSRs, or use the
registered version of the program.
Boot record cannot be read
The boot record of the disk may be invalid.
Directory not found
The directory to scan specified on the command line was not
found. Check that it exists and try again.
As each file is checked it will be tagged. These are the tags.
OK - the file is clean.
infected - the file contains a vir
