│■INTRODUCTION │
└──────────────┘

ARJVIR is a small program allowing you to fastly and safely scan against
virii for all kind of ARJed files, without being forced to use long and
obnoxious check routines. Using directly Robert K. Jung's ARJ.EXE to
minimize problems in decoding and treating the archives, as well as
McAfee's SCAN.EXE which is shareware and widely distributed. We believe
that all of this makes ARJVIR a very safe and updateable program that will
serve you well in the war against viruses in ARJed files.

ARJVIR was created mainly to make life easier to BBS operators (SYSOPS),
allowing them to check on the spot the received files, and to protect
their systems as well as their users against the threat of viruses.

ARJVIR can also be used in companies desiring to get a software that can
check against virii in their files while having only minimal knowledge of
how to handle those files and of the programs used to perform those
verifications (i.e. SCAN.EXE & ARJ.EXE). Also ARJVIR allows the single user
to perform on a personnal base checks against virii infection.

│■ARJVIR CHARACTERISTICS │
└────────────────────────┘

   ∙Allows to verify files with ARJ.EXE whatever the ARJ format used
    (*.ARJ, *.EXE, *.A01, *.???)

   ∙Allows mass treatment of files with [*.*] and [????????.???]
    providing fast verification of a large quantity of archives, whichever
    the format used (*.EXE, *.ARJ, *.A0?...A??...)

   ∙Optionnal verification of the computers memory before any verification,
    to detect any infection by memory-resident viruses.

   ∙Creation of a report allowing to trace back not only the infected
     archives but also which files in the archive are actually infected.
    Identifies the virii in cause, making it easier to remove afterwards.

   ∙This report also lists any defective archive, and archives that are of an
     unknown type.

   ∙Works from 8086 through 80586

│■REQUIRED HARDWARE AND SOFTWARE │
└────────────────────────────────┘

ARJVIR uses very few memory space, but hard disk space is critical for
the program to perform well. Rule of thumb: Always keep two times the file
size (or of the biggest file scanned) in free space to avoid problems.
(i.e. 300k file, have at least 600k of free disk space)

ARJVIR must be installed on your hard drive, but takes a mere 30K installed
with full documentation.

ARJVIR has been tested and works well with the following programs:

ARJ 2.41a            SCAN 9.21 v.111
ARJ 2.41             SCAN 9.17 v.108
ARJ 2.39f (beta)     SCAN 9.17 v.106
ARJ 2.30             SCAN 9.17 v.102

MSDOS 6.20
MSDOS 6.00
MSDOS 5.00
MSDOS 4.01
MSDOS 3.30

Moreover, there's no problem using ARJVIR in a MS-WINDOWS DOS session or
DOS full screen session.

┌───────┐
│■USAGE │
└───────┘

ARJVIR's syntax is the following:

ARJVIR [Filename.ext]
Default extension is: .ARJ

Where [Filename.ext] represents the name of the file to check.

If it's an ordinary ARJ file (*.ARJ), a self-extractable ARJ file produced
with the switches -je or -je1 (*.EXE) or a multi-volume archive (*.a01)
simply enter the filename followed by the extension.

I.E. ARJVIR diskutil.arj
     ARJVIR sysutil.exe
     ARJVIR backup.a01

Mass treatment is especially useful for archives of several mixed types
(i.e. *.ARJ with *.A01) etc.

I.E. ARJVIR *.*
     ARJVIR programs.*
     ARJVIR backup.a0?

Finally to obtain information about the program, as well as the options
or how to join the authors, simply type ARJVIR /?

│■INSTALLATION │
└──────────────┘

To install ARJVIR on your system, simply type INIMAKER in the directory
where you have your ARJVIR files. Answer the questions and that's all!
If the files ARJ.EXE and SCAN.EXE are not found within your path, they must
be entered manually in the file ARJVIR.INI afterwards in order to complete
the installation.

The option "Memory verification" is highly recommended since
it's your only protection against memory-resident virii. Note that when
treating many archives, the memory is only checked once before the process,
to limit scanning time to reasonnable proportions.

┌──────────────────┐
│■ABOUT ARJVIR.INI │
└──────────────────┘

This file, which is absolutely necessary to ARJVIR is as follow:

C:\UTIL\SCAN.EXE
C:\UTIL\ARC\ARJ.EXE
MEMCHECK:YES
0

C:\UTIL\SCAN.EXE Represents the path to the file SCAN.EXE. Note that it is
necessary to put the filename WITH the full extension.

C:\UTIL\ARC\ARJ.EXE Same as above.

MEMCHECK:(YES/NO) Allows ARJVIR to perform scanning of the memory prior to
scanning the ARJed files. If upon startup you have a memory checking
anti-virus program, you may want to disable this feature.

0 is the pause in seconds after the occurence of an error message. This
allows you to follow in real time what's going on. Since it would be most
impractical in batch mode, the default value is set to 0. Values can range
from 0 to 10 and if not between this range, will automatically be set to 0.

  ALL ENTRIES IN THE FILE ARJVIR.INI MUST BE IN UPPERCASE!!!

Otherwise ARJVIR may perform erratically. Furthermore, the path to SCAN.EXE
MUST occupy the first line, and the path to ARJ.EXE the second one. Finally,
MEMCHECK: must be on the third line. To avoid problems, do not change the
syntax of Memcheck except for a change from YES to NO and the inverse.

In case of problems, copy the above example of ARJVIR.INI and complete with
your own parameters (path, etc.). Don't forget that all paths must be
entered in UPPERCASE. If you really have to put comments in the ARJVIR.INI
file, do so on line 5 and subsequent.

└───────────────────────┘

This is the resulting file from the verification performed by ARJVIR.
The time and date as well as the verification parameter. Here's a small
example of what it looks like:

Session start: 15:26:19  On: 02/01/1994             <--Session starts
Verification parameter : PLAK*.ARJ                  <--Self-explanatory

]] Verification of file: PLAK1.ARJ...........[√]    <-- file passed test

]] Verification of file: PLAK2.ARJ...........[√]    <-- file passed test

]] Verification of file: PLAK3.ARJ...               <-- file didn't passed ARJ
                                                       test, hence no checkmark
Error encountered at: 15:26:28  On: 02/01/1994
Fatal error. The archive PLAK3.ARJ is damaged or ARJ.EXE is corrupted

]] Verification of file: PLAKVIR.ARJ.........[√]    <-- file passed ARJ test
                                                        valid ARJ file

  The virus Flash [Flash] was found
Verification C:.\VIR_5.EXE
  The virus Viper [Vip] was found
Verification C:.\VIR_7.COM
  The virus Leprosy-3 [Lep3] was found

(This list allows you to know what files are actually infected and by which
strands of viruses. This allows cleaning afterwards, should you wish to do so)

Directory C:.contains 31 files.     (number of files in PLAKVIR.ARJ)
