Designed to safely detect and remove all known strains of the W95.CIH (Chernobyl) virus (known strains as of August 3rd, 1998) from memory under Windows 95 and Windows 98 (the W95.CIH virus cannot infect Windows NT systems). If the tool is run before the virus has infected the system, itwill also 'inoculate' the computer's memory to prevent the W95.CIH virus from infecting the system until the next system reboot.
