They are intended to provide the person with a virus infection an emergency means to identify and remove an infection. They are not meant to replace the program documentation. Please read through the documentation for detailed instructions. Files ending in a .DOC extension have been formatted for printing on a printer with a minumum of 60 lines per page. Files ending in a .TXT extension have not been formatted. VIRUSCAN (SCAN) 1. Copy all the VIRUSCAN files to a floppy disk in drive A:. 2. WRITE PROTECT THE DISK!!! 3. Insert the disk into the infected PC and type: A:\SCAN C: D: E: This will allow VIRUSCAN to run on the C:, D:, and E: drives. If you do not have D: and E: drives, leave them out. 4. If infected files are found, they may be ERASED by running VIRUSCAN with the /D (overwrite and delete) option: A:\SCAN C: D: E: /D Running VIRUSCAN with the /D option will delete files in a way that is non-recoverable. Use this option only if you do NOT want to recover any of the infected files. Otherwise use the CLEAN-UP universal virus disinfector. 5. Turn computer off to remove the virus from memory. CLEAN-UP (CLEAN) 1. Copy all the CLEAN-UP files to a floppy disk in drive A:. 2. WRITE PROTECT THE DISK!!! 3. Power down the infected system and then boot from a clean, write protected system master diskette. This must be done to remove any viruses from memory that may interfere with the virus removal process. NOTE: If you are unable to access your hard disk after booting from a floppy, check to make sure that any special device drivers needed to use the hard disk are on the floppy and run from the CONFIG.SYS or AUTOEXEC.BAT file. 4. Insert the CLEAN-UP disk into the A: drive of the infected PC and type: A:\CLEAN C: D: E: [virus-ID-code] This will allow CLEAN-UP to disinfect viruses on the C:, D:, and E: drives. If you do not have D: and E: drives, leave them out. For the Jerusalem virus, the ID code is [JERU]. For the Stoned virus, the ID code is [STONED]. For other viruses, use the ID code generated by SCAN, or check the VIRLIST.TXT file. Remember to include the square brackets, "[" and "]." If you are disinfecting a file-infecting virus, such as the Jerusalem, it is recommended that you add the /A switch to the command line to check all files. This will ensure that the virus is removed from any overlay files that may not use the defaault overlay extensions recognized by CLEAN-UP. If you know that none of your programs use overlays, then the /A switch is not necessary. If more than one virus type was detected, then CLEAN-UP will have to be run for each type of virus. 5. Turn the computer off and then re-boot from the hard disk. AN IMPORTANT NOTE You have now completed a virus disinfection of your computer system, however, you may have other computers and floppy disks that are infected. You know have a clean PC from which to scan and clean them. Please now take the time to read through the VIRUSCAN and CLEAN-UP documentation to show you the fastest and safest way of removing your computer virus infection.
