- 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
- eradicates all viruses identified by the current version of
- VIRUSCAN (SCAN). CLEAN will also remove unknown (new) viruses
- from .COM and .EXE files, the partition table, and boot sector
- using recovery information stored by the VIRUSCAN program [See
- the VIRUSCAN documentation for more details].
- CLEAN runs on any PC with 320Kb 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 that
- it has been damaged, a new, clean copy should be obtained.
- CLEAN is packaged with VALIDATE, a program that checks
- the integrity of the CLEAN.EXE file. The VALIDATE.DOC file
- describes its usage. The VALIDATE program distributed with
- CLEAN may be used to check subsequent versions.
-
- The validation results for Version 8.6B95 should be:
-
- FILE NAME: CLEAN.EXE
- SIZE: 98,237
- DATE: 08-19-1992
- FILE AUTHENTICATION
- Check Method 1: BE92
- Check Method 2: 02BB
-
- 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 or from the
- Computer Virus Help Forum on CompuServe (GO VIRUSFORUM).
- Beginning with Version 72, all McAfee Associates programs
- are archived with PKWare's PKZIP Authentic File Verification.
- If you do not see the "-AV" message after every file is unzipped
- and receive the "Authentic Files Verified! # NWN405 Zip Source:
- McAFEE ASSOCIATES" message when you unzip the files then do not
- use them. If your version of PKUNZIP does not have verification
- ability, this message may not be displayed. Please contact
- McAfee Associates if you think the .ZIP file has been damaged.

-
- WHAT'S NEW
-
- Version 95C replaces Version 95B that displayed a
- corruption warning because of a validation code problem
- CLEAN-UP has been updated to recognize the new viruses
- added in the 8.7B95 version of VIRUSCAN.
-
- 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.

- *Denotes virus with more than one strain
- +Denotes virus which attaches to overlays
-
- AN IMPORTANT NOTE ABOUT .EXE FILES: Some viruses infecting .EXE
- files may not be removed successfully if the .EXE loads itself
- as an internal overlay. Instead of attaching to the end of the
- .EXE file, the virus may attach to the beginning of the overlay
- area, and corrupt the program. CLEAN will truncate files
- infected in this manner. If a file no longer runs after being
- cleaned, replace it from the manufacturer's 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.

-
-
- 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 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 d1: ... d26: [virus I.D.] /A /E .xxx .yyy. .zzz /FR
- /GENERIC /GRF filename /MAINT /MANY /M
- /NOEXPIRE /NOPAUSE /REPORT d:filename /SP
- /UNATTEND
-
- Options are:
-
- /A - Check all files for viruses
- /E .xxx .yyy .zzz - Clean overlay extensions .xxx .yyy .zzz
- /FR - Display messages in French
- /GENERIC - Clean unknown viruses
- (see below for specifics)
- /GRF filename - Clean unknown viruses using recovery
- data file
- /MAINT - Clean "invalid media" error (damaged)
- disk
- /MANY - Check multiple floppies
- /NOEXPIRE - Do not display expiration notice
- /NOPAUSE - Disable screen prompting
- /REPORT filename - Create report of cleaned files
- /SP - Display messages in Spanish
- d1: ... d26: - indicate drives 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.)
-
- NOTE: The square brackets "[" and "]" are required.
-
- CLEAN-UP Version 8.6B95 Page 6
-
-
- The /A option checks all files on the disk. This should
- be used only if a file-infecting virus is detected. This option
- takes priority over the /E option.
-
- The /E option allows the user to specify an extension or
- set of extensions to clean. Extensions should include a period
- "." and each extension must be separated by a space. Up to
- three extensions may be added with the /E. If more extensions
- are required, use the /A option instead.
-
- The /FR option tells CLEAN to display all messages in
- French. This option cannot be used with the /SP (Spanish)
- option.
-
- The /GENERIC 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.
-
- The /GRF 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. The syntax is /GRF filename, where
- "filename" drive, path and name of the recovery file used. When
- using the /GRF option, no virus I.D. code is required for CLEAN.
-
- The /MAINT option is used to clean hard disks partitioned
- with MS-DOS 4.0 or above that have been damaged by a boot sector
- or partition table virus. Disks damaged in this manner give an
- "invalid media" message whenever accessed. The /MAINT option
- cleans the partition table and boot sector only.
-
- The /MANY option is used to clean multiple floppy disks.
- 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.
-
- The /NOEXPIRE option disables the warning message from
- CLEAN displayed after seven months warning that it may no longer
- be current with respect to known viruses.
-
- The /NOPAUSE option disables the "More? (H = Help)" prompt
- displayed when CLEAN fills a screen with messages. This
- allows CLEAN to be run on PC's with severe infections sans
- operator assistance.
-
- The /REPORT option saves a list of infected files to
- disk in ASCII text format. If a report exists, it will be
- overwritten with the new report. The syntax is /REPORT filename
- where "filename" is the drive, path and name for the report
- file.
- CLEAN-UP Version 8.6B95 Page 7
-
-
- The /SP option tells CLEAN to display all messages in
- Spanish. This option can not be used with the /FR (French)
- option.
-
