 General Comments: 
       The Immolation virus was submitted in May, 1993.  Its origin is 
       unknown.  Immolation is a non-resident, direct action overwriting 
       virus which infects .EXE programs. 
       When a program infected with the Immolation virus is executed, this 
       virus will infect two .EXE programs larger than the virus itself 
       which are located in the current directory or along the system 
       path.  A system hang may then occur.  Infected programs will not 
       function properly. 
       Programs infected with the Immolation virus will have the first 
       663 bytes of the host program overwritten by the Immolation viral 
       code, permanently corrupting them.  The file's date and time in the 
       DOS disk directory listing will not be altered.  One text string 
       is visible within the Immolation viral code in infected programs: 
       The Immolation virus activates on any Monday before 9:00 AM, at 
       which time the system will be rebooted when an infected program 
       is executed.  On Fridays after 12:00 noon, the virus will change 
       the amount of available memory to 64K when an infected program 
       is executed.  Finally, one all of the .EXE programs in the 
       current directory and along the system path have been infected, the 
       virus will lockup the system when the next infected program is
