Note: The W95.CIH virus cannot infect computers running on Windows NT, 2000, or XP.
Download the KILL_CIH.EXE file to the Windows desktop.
Close all the programs before running the tool.
Run KILL_CIH.EXE while in a DOS window within Windows as follows:
Click Start, and then click Run.
Type command, and then click OK.
(An MS-DOS window will open to the C:\WINDOWS\Desktop prompt.)
Type kill_cih.exe, and then press Enter.
The KILL_CIH.EXE program does not require command-line arguments. It will display one of several different messages upon completion:
"The W95.CIH virus was found in memory. The W95.CIH virus has been successfully disabled. You can now run Norton AntiVirus to remove any infections from files."
This message is displayed if any strain of the W95.CIH virus is found in the computer's memory. The tool has disabled the virus in memory and will prevent it from causing damage to the system or infecting any additional files. At this point, it is safe to run NAV to remove the virus from the system.
"The W95.CIH virus was not found in memory."
This message is displayed if known strains of the W95.CIH virus are not found in memory. The tool has inoculated the computer and will prevent the virus from infecting system memory, if an infected file is run during the remainder of the computer session (until reboot). At this point, it is safe to run NAV to remove the virus from the system.
"Warning: This Windows NT system cannot be infected by the W95.CIH virus."
This message will be displayed if the tool is used under Windows NT/2000/XP. There is no harm in doing this, and the program will normally exit after displaying this message
