CheckOut is a virus protection program which is intended for use in
environments in which many program reside in archives such as ZIP or
LZH. It breaks open each archive and calls ViruScan by McAfee
Associates to check the components for viral problems. If desired, it
can then repackage the archive in a different format (e.g. convert
.zip to .arj). Both the filelists of opus/fido systems (files.bbs) as
well as PCBoard systems (DIRN, DIRNG) are converted in the process. It
will also work on a much simpler level where the user has an
occasional file to be scanned or re-archived.
FEATURES:
- Handles nested files to any level.
- Desqview compatibility
- Optionally moves infected files or bad archives out of the way.
- Each file process is logged and identified as ok or bad in some
sense.
- Control is passed to named batch files at two times so that
comments can be added to the rearchived file, or files can be
added to the package, etc.
- Sensitive to read-only files.
- Processed files can be identified so the same directory can be
processed each night and only the new files treated.
- Single files can be specified for scanning, conversion or both.
- Can be operated either in an interactive mode with menus or from
the command line, or batch
- Menu mode can be used to write a batch file for subsequent use.
- Can be stopped anytime and pick up where it left off.
- Handles Opus and Fido files.bbs automatically
- Handles PCBoard DIRn and DIRng files automatically.
- Moves good files along a specified path
- Pathnames are maintained on archievers that handle pathnames.
The quality of the program as well as the feature set, has been
enhanced considerably by the beta testers who did everything that
could be expected and more. These include: Patricia M. Hoffman, 204/869,
Robert Michal, 386/451, and John Alton, 141/250.
Special thanks are due to Patricia Hoffman who independently tested
CheckOut with live strains of Jerusalem-B, AIDS, Alabama, Dark
Avenger, MIX!/Saratoga, Zero-Bug, 2930 (Traceback), Yankee Doodle,
3551/Syslock, and DataCrime II.
LIMIT OF LIABILITY
CheckOut is distributed as is. The author makes no representation

SUPPORT
There is no staff employed for support purposes. If you have a
problem to report or features you would like to see implemented,
use the comment field on the registration form. All suggestions will
be evaluated for the next version.
SHAREWARE
CheckOut is distributed as shareware. This means you can evaluate
the product before you decide to register it. If you are using it
after a couple of weeks, you should register it. You can copy CheckOut
or any shareware program and distributed to anyone else, provided that
neither the program nor the documentation is altered and that you do
not charge a fee. Because there is no advertising, distribution, or
packaging cost, the price of a shareware program is often less than an
equivalent package sold through retail channels.
The registration form is provided in a separate file.
INTRODUCTION INTRODUCTION ////////////
ViruScan or SCAN has become one of the most popular methods of
checking for various types of viruses. It will check boot sector and
each file potentially a virus carrier on a disk for the identifying
characteristics of hundreds of different virus types. For most users,
this is exactly what is needed. However, for people that operate a BBS
or make extensive use of BBS files, most executable files reside
within compressed or archived files and these can't be processed by
SCAN.
CheckOut makes it possible for SCAN to check the files within
archives. It operates by stepping through each file in a subdirectory,
looking at the extension, spawning the appropriate unarchive program
(I.e. LHARC, PAK, PKUNZIP, ZOO, PKUNPAK) and then spawning SCAN to
test each of the components of the archived file.
As CheckOut decompresses files and checks the components for viri,
a log is being written stating that the file has been checked and
whether or not it is found to be infected. Additionally, the file
itself can be marked as having been checked. If there is a problem
with the integrity of the archive, that fact is also noted in the log.
CheckOut will cause each EXE, COM, OVL, BIN, PIF, and SYS file as
well as each ARC, PAK, ZIP, LZH, ZOO, SDN, ARJ, in the specified
subdirectory to be scanned. The files which are not processed include
those with a different extension than those noted above. Most of these
will be data files, and since they are not executed, they can't do any
harm. However, self-extracting archives are potentially harmful and
are missed by both SCAN and the current version of CheckOut. CheckOut
sees the "EXE" and thinks SCAN will check it and SCAN thinks it did
check (it did, but for the wrong strings). The code exists now to
process self-extracting archives, but was not included in this version
because it can be outwitted fairly easily. It may be more muscular by
the time the next version is released.
SETUP:
Each program that is to be used must be located on the path. No
check is made, so if you don't use a compression type, you don't need
the uncompressor. In the case of SCAN, a check is first made of the
directory that CheckOut was executed from. If SCAN is located there,
that one is used in preference to a version somewhere else on the
path. The filenames that CheckOut might look for include:
LHA.EXE
PKUNZIP.EXE
PKZIP.EXE
ZOO.EXE
PKUNPAK.EXE
PKPAK.EXE
PAK.EXE
SCAN.EXE
ARJ.EXE
These programs must exist on the path if they are to be used. They
can not be renamed, and they must be recent enough to handle the files
which will be processed. The version of SCAN must be 9.1V97 or
greater (SCANV97) because CheckOut uses f
