SYNOPSIS
CLEAN-UP (CLEAN) is a virus disinfection program for IBM PC
and compatible computers. CLEAN searches through the partition
table, boot sector, or files of a PC to remove viruses specified
by the user. In most instances, CLEAN repairs infected areas
of the system, restoring them to their pre-infected state.
CLEAN removes all viruses identified by the current version of
VIRUSCAN. CLEAN can also remove new or unknown viruses using
recovery information stored by SCAN [See VIRUSCAN's
documentation for details].
CLEAN runs on any PC with 400Kb and DOS 2.00 or above.
AUTHENTICITY
CLEAN performs a self-test when run. If CLEAN has been
modified in any way, a warning will be displayed. However,
CLEAN is still able to remove viruses. If CLEAN reports it
has been damaged, a new, undamaged copy should be obtained.
CLEAN is packaged with VALIDATE, a program to check
the integrity of CLEAN.EXE. The VALIDATE.DOC file explains
its usage. The VALIDATE program distributed with CLEAN may
be used to check new versions for tampering or damage.
The validation results for Version 106 should be:
FILE NAME: CLEAN.EXE
SIZE: 178,397
DATE: 09-13-1993
FILE AUTHENTICATION
Check Method 1: 6347
Check Method 2: 0E2F
If your copy of CLEAN.EXE differs, it may have been modified.
Always obtain CLEAN from a known source. The latest version of
CLEAN and validation data can be obtained from McAfee
Associates' bulletin board system at (408) 988-4004, from the
McAfee Virus Help Forum on CompuServe (GO MCAFEE), and by
anonymous ftp from the mcafee.COM site on the Internet.
All of McAfee Associates' programs are archived with
Version 1.10 of PKWare's PKZIP Authentic File Verification.
When unzipped with Version 1.10 of PKWare's PKUNZIP program,
an "-AV" will be displayed after each file is unzipped and an
"Authentic Files Verified! # NWN405 Zip Source: McAFEE
ASSOCIATES" will appear once all files are unzipped.
NOTE: If you do not receive the Authentic File Verification
messages, you may be using a different version of
PKUNZIP, such as V1.93α or V2.04. Use PKUNZIP Version
1.10 to unzip files if you wish to have Authenticity
Verification displayed as files are unzipped.
CLEAN-UP Version 9.19 V108 Page 3
WHAT'S NEW
Version 108 adds disinfection of both the Chile Mediera,
and of the Loren viruses.
CLEAN displays messages in English (default); refer to
APPENDIX C for information on displaying messages in other
languages.
Please refer to the enclosed VIRLIST.TXT file for a short
description of the new viruses. For more detailed descriptions,
please refer to Patricia Hoffman's virus summary listing (VSUM).
OVERVIEW
CLEAN searches the system for viruses to remove. When an
infected file is found, CLEAN isolates and removes the virus and
in most cases repairs the infected file and restores it to
normal operation. If the file is infected with an uncommon
virus, CLEAN displays a warning message asking whether to
overwrite and delete the infected file. Erased files are non-
recoverable.
Before running CLEAN, verify the infection with VIRUSCAN.
SCAN will locate and identify the virus and provide the I.D.
code used by CLEAN. The I.D. is displayed inside the square
brackets, "[" and "]." For example, the I.D. code for the
Jerusalem virus is displayed as "[Jeru]". This I.D. must
be used with CLEAN to remove the virus. The square brackets
"[" and "]" MUST be included.
If SCAN finds an unknown virus in a file that has had
validation or recovery data stored for it, it will warn that an
infection has occurred. It will not, however, display an I.D.
code.
NOTE: When CLEAN is run with the /GENERIC or /GRF options
to disinfect files or system areas based on recovery
information stored by SCAN, no I.D. code should be
used.
Please refer to the VIRUSCAN documentation for instructions
in adding recovery information to your system.

AN IMPORTANT NOTE ABOUT .EXE FILES: Some viruses damage .EXE
files when they infect them if the file being infected loads
overlays internally. CLEAN will truncate files infected in
this manner. If a file no longer runs after being cleaned,
replace it from the original disk or virus-free backups.
AN IMPORTANT NOTE ABOUT PARTITION TABLE VIRUSES (e.g., Stoned):
Removing a partition table-infecting virus like the Stoned
can cause loss of the partition table on systems partitioned
with programs other than DOS, e.g., Disk Manager or SpeedStor.
As a precaution, back up all critical data before running CLEAN.
Loss of the partition table can result in the LOSS OF ALL DATA
ON THE DISK.
CLEAN-UP Version 9.19 V108 Page 5
OPERATION and OPTIONS
IMPORTANT NOTE: TURN OFF YOUR PC AND BOOT FROM A CLEAN DOS
SYSTEM-BOOTABLE DISK BEFORE BEGINNING. RUN
CLEAN FROM A WRITE-PROTECTED DISK TO PREVENT
INFECTION OF THE CLEAN.EXE PROGRAM FILE.
Power down the infected system and boot from a clean,
write-protected system-bootable diskette. This insures that the
virus is not in system memory and prevents reinfection. After
cleaning, power down the PC, boot from the system disk, and run
VIRUSCAN to ensure the system has been successfully disinfected.
After cleaning the hard disk, copy the SCAN and CLEAN programs
on to it and check all floppy disks that have been in
contact with the system.
CLEAN displays the name of infected files or system areas,
the virus found, and reports a "successful" disinfection for
each virus removed. If a file has multiple infections, CLEAN
will report the virus has been removed successfully for each
infection.
Select valid options for CLEAN-UP from the list below:
CLEAN {drive(s)} [virus I.D.] {options}
^
|
`---- NOTE: The square brackets "[" and "]"
are required around the I.D. code.
Options are:
{drives} - indicate drive(s) to be cleaned
[virus I.D.] - Virus identification code provided by
SCAN when a virus is detected (See the
VIRLIST.TXT file for a complete list.)
/A - Check all files for viruses
/AD{x} - Clean all drives {L = Local, N = Network}
/E .xxx .yyy .zzz - Clean overlay extensions .xxx .yyy .zzz
/GENERIC - Clean unknown viruses
(see below for specifics)
/GRF {filename} - Clean unknown viruses using recovery
data file {filename}
/MANY - Check multiple disks for viruses
/NOEXPIRE - Do not display expiration notice
/NOPAUSE - Disable screen prompting
/REPORT {fname} - Create report file {fname}
CLEAN-UP Version 9.19 V108 Page 6
/A - This option checks all files on the drive(s) scanned and
also examines a greater portion of files. This substantially
increases the amount of time required to check disks and also
increases CLEAN's ability to detect viruses infecting overlay
files. It is recommended this switch only be used when an
overlay-infecting virus is found. This option takes priority
over the /E option.
/AD{x} - This option cleans all drives of viruses. If /ADL
is used, all local drives are checked, including compressed
drives and CD-ROM's. If /ADN is used, all networked drives
are checked. To clean local and network drives, use /AD by
itself.
/E .xxx .yyy .zzz - This option allows additional extension(s)
to be cleaned. Extensions should include a period "." and each
extension must be separated by a space after the /E. Up to
three extensions may be added with the /E. For more extensions,
use the /A option instead.
/GENERIC - This option is used to clean files or system areas
that have been infected with a new (unknown) virus. For
/GENERIC to work, recovery information must have been stored
prior to infection by VIRUSCAN's /AG option. No virus I.D. code
is required when using the /GENERIC switch.
/GRF {filename} - This option is used to clean files or system
areas that have been infected by a new (unknown) virus. For
/GRF to work, recovery data and validation codes must have been
saved by VIRUSCAN's /AF option to {filename}. No virus I.D.
code is required when using the /GRF switch.
/MANY - This option is used to clean multiple disks placed in
the same drive. If you have more than one floppy disk to check
for viruses, the /MANY option allows you to check them without
running CLEAN multiple times.
/NOEXPIRE - This option disables a warning message that CLEAN
displays after seven months warning that it may no longer be
current with respect to known viruses.
/NOPAUSE - This option disables the "More? (H = Help)" prompt
displayed when CLEAN fills up a screen with 24 lines of text.
This allows CLEAN to be run on PC's with severe infections
without user assistance.
/REPORT {filename} - This option saves the output of CLEAN to
{filename} in ASCII text format. If {filename} exists, CLEAN
will erase it and create a new report

CLEAN-UP Version 9.19 V108 Page 9
APPENDIX A: CLEAN-UP'S FOREIGN LANGUAGE SUPPORT
CLEAN-UP can display messages in a foreign language by
reading in a replacement set of messages from an external
file named MCAFEE.MSG. When the MCAFEE.MSG file is placed in
the same directory as the SCAN.EXE file, SCAN will display
messages from the foreign language module instead of displaying
messages in English (American). Currently, SCAN is bundled with
two .MSG files, FRENCH.MSG and SPANISH.MSG, which contain
messages in French (European) and Spanish (Latin America),
respectively.
To use a foreign language module, rename it to MCAFEE.MSG
and place it in the same directory as the CLEAN.EXE file. When
CLEAN-UP is run, it will check for the MCAFEE.MSG file and use it,
if found.
Support for other languages such as Chinese, Dutch, Finnish,
French (Canadian), German, Hungarian, Norwegian, Portuguese,
Russian, Spanish (European), Swahili, Swedish and Bulgarian is
planned for future releases. Contact your local McAfee Associates
Authorized Agent or McAfee Associates directly for availability.
