- SYNOPSIS
-
- CLEAN-UP (CLEAN) is a virus disinfection program for IBM PC
- and compatible computers. CLEAN-UP will search though the
- partition table, boot sector, or files of a PC and remove a virus
- specified by the user. In most instances CLEAN-UP is able to repair
- the infected area of the system and restore it to normal usage.
- CLEAN-UP works on all viruses identified by the current version of
- the VIRUSCAN (SCAN) program.
- CLEAN-UP runs on any PC with 256Kb and DOS 2.00 or above.
-
-
- AUTHENTICITY
-
- CLEAN-UP runs a self-test when executed. If CLEAN has been
- modified in any way, a warning will be displayed. The program will
- still continue to remove viruses, though. If CLEAN reports that
- it has been damaged, is recommended that a new, clean copy be
- obtained.
- CLEAN-UP is packaged with the VALIDATE program to ensure the
- integrity of the CLEAN.EXE file. The VALIDATE.DOC instructions
- tell how to use the VALIDATE program. The VALIDATE program
- distributed with CLEAN-UP may be used to check all further versions
- of CLEAN.
-
- The validation results for Version 77 should be:
-
- FILE NAME: CLEAN.EXE
- SIZE: 85,569
- DATE: 04-25-1991
- FILE AUTHENTICATION
- Check Method 1: 4143
- Check Method 2: 1D52
-
- If your copy of CLEAN.EXE differs, it may have been modified.
- Always obtain your copy of CLEAN-UP from a known source. The
- latest version of CLEAN-UP and validation data for SCAN.EXE can be
- obtained off of McAfee Associates' bulletin board system at (408)
- 988-4004.
- Beginning with Version 72, all McAfee Associates programs for
- download 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 message "Authentic Files Verified!
- # NWN405 Zip Source: McAFEE ASSOCIATES" when you unzip the files
- then do not run them. If your version of PKUNZIP does not have
- verification ability, then this message may not be displayed.
- Please contact McAfee Associates if your .ZIP file has been
- tampered with.

- WHAT'S NEW
-
- Version 77 adds nineteen viruses to the list of computer
- viruses that can be safely removed. They are the 555, 651, 3066,
- Air Cop, Beeper, Black Monday, Den Zuk, Fellowship, Filler, Ghost
- Korea, Lazy, Lisbon, Mardi Brothers, Murphy, Print Screen-2, RPKS,
- Striker, and Typo Boot viruses. For more information about these
- viruses, please refer to the accompanying VIRLIST.TXT file.
- Additionally, a new command, /NOPAUSE, has been added. When
- CLEAN is run with the /NOPAUSE option it will not stop when it
- fills the screen with messages.
-
-
- OVERVIEW
-
- CLEAN-UP searches the system looking for the virus you wish
- to remove. When an infected file is found, CLEAN-UP 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 a
- less common virus, CLEAN-UP will then display a warning message and
- prompt the user, asking whether to overwrite and delete the
- infected file. Files erased in such a manner are non-recoverable.
- Verify the suspect virus infection with the VIRUSCAN program
- before running CLEAN-UP. VIRUSCAN will locate and identify the
- virus and provide the I.D. code needed to remove it. 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-UP to remove the
- virus. The square brackets "[" and "]" MUST be included.
- The common viruses that CLEAN-UP is able to remove
- successfully and repair and restore the damaged programs are:
-
- 555 651 1260 15xx
- 170x 4096* Air Cop Alabama
- Alameda Ashar* Azusa Beeper
- Black Monday Bloody! Dark Avenger* DataLock
- Disk Killer* EDV* Fellowship Filler
- Fish Flip Ghost Invader*
- Jerusalem* Joshi KeyPress* Korea *
- Lazy Liberty Lisbon* Mardi Brothers
- Murphy* Music Bug New Jerusalem Pakistani Brain*
- PayDay Ping Pong* Plastique* Print Screen-2*
- RPKS Slow Stoned* Striker
- SunDay Suriv03 Taiwan 3 Taiwan 4
- Typo Boot V800 VacSina* Vienna*
- Violator* Whale Yankee Doodle* ZeroBug
- *Denotes virus with more than one strain

-
- AN IMPORTANT NOTE ABOUT .EXE FILES: Some viruses which infect .EXE
- files can not be removed successfully in all cases. This usually
- occurs when the .EXE file loads internal overlays. Instead of
- attaching to the end of the .EXE file, the virus may attach to the
- beginning of the overlay area, and program instructions are
- overwritten. CLEAN-UP will truncate files infected in this manner.
- If a file no longer runs after being cleaned, replace it from the
- manufacturer's original disk.
-
- AN IMPORTANT NOTE ABOUT THE STONED VIRUS: Removing the Stoned
- virus can cause loss of the partition table on systems with
- non-standard formatted hard disks. As a precaution, backup all
- critical data before running CLEAN-UP. Loss of the partition table
- can result in the LOSS OF ALL DATA ON THE DISK.
-
-
- OPERATION:
-
- IMPORTANT NOTE: POWER DOWN YOUR SYSTEM AND BOOT FROM A CLEAN
- SYSTEM DISK BEFORE BEGINNING. RUN THE CLEAN-UP PROGRAM FROM A
- WRITE-PROTECTED DISK TO PREVENT INFECTION OF THE PROGRAM.
-
- Power down the infected system and boot from a clean,
- write-protected system diskette. This step will insure that the
- virus is not in control of the computer and will prevent
- reinfection. After cleaning, power down the system again, reboot
- from the system disk, and run the VIRUSCAN program to make sure the
- system has been succesfully disinfected. After cleaning the hard
- disk, run the VIRUSCAN program on any floppies that may have been
- inserted into the infected system to determine if they have been
- infected.
- CLEAN-UP will display the name of the infected file, the virus
- found in it, and report a "successful" disinfection when the virus
- is removed. If a file has been infected multiple times by a virus
- (possible if the virus does not check to see if it has already
- attached to a file) than CLEAN-UP will report that the virus has
- been removed successfully for each infection.

-
- To run CLEAN-UP type:
-
- CLEAN d1: ... d10: [virus ID] /A /E .xxx /FR /MANY /M /REPORT
- d:filename /NOPAUSE
-
- Options are:
-
- /A - Examine all files for viruses
- /E .xxx .yyy .zzz - Clean overlay extensions .xxx .yyy .zzz
- /FR - Display messages in French
- /MANY - Check and disinfect multiple floppies
- /NOPAUSE - Disable screen prompting
- /REPORT d:filename - Create report of cleaned files
-
- d1: ... d10: - indicate drives to be cleaned
- [virus ID] - Virus identification code - provided by the
- VIRUSCAN program when it detects a virus.
- For a complete list of codes, see the
- accompanying VIRLIST.TXT file
-
-
- The /A option will cause CLEAN to go through all files on
- diskette. This should be used if a file-infecting virus is
- detected.
- The /E option allows the user to specify an extension or set
- of extensions to clean. Extensions must be separated by a space
- after the /E and between each other. Up to three extensions may
- be added with the /E. For more extensions, use the /A option.
- The /FR option tells CLEAN-UP to display all messages in
- French instead of English.
- The /MANY option is used to clean multiple floppy diskettes.
- If the user has more than one floppy disk to check for viruses, the
- /MANY option will allows the user to check them without having to
- run CLEAN multiple times.
- The /NOPAUSE option disables the "More..." prompt that appears
- when CLEAN fills a screen with data. This allows CLEAN-UP to run
- on a machine with multiple infections without requiring operator
- intervention when the screen fills up with messages from the CLEAN
- program.
- The /REPORT option is used to generate a listing of
- disinfected files. The resulting list can be saved to disk as an
- ASCII text file. To use the report option, specify /REPORT on the
- command line, followed by the device and filename.
