 General Comments: 
       The Terminator virus was submitted in April, 1992.  Its origin is 
       unknown.  Terminator is a memory resident infector of .COM 
       programs, including COMMAND.COM. 
       The first time a program infected with the Terminator virus is 
       executed, the Terminator virus will install itself memory resident 
       as a low system memory TSR of 1,104 bytes.  Interrupts 21, 22, and 
       24 will be hooked. 
       Once the Terminator virus is memory resident, it will infect .COM 
       programs, including COMMAND.COM, when they are executed.  Programs 
       infected with the Terminator virus will have a file length increase 
       of 526 bytes with the virus being located at the end of the program. 
       The file's date and time in the DOS disk directory listing will 
       have been updated to the system date and time when infection 
       Systems infected with the Terminator virus may notice that when 
       the user attempts to execute .COM programs from a write-protected 
       diskette, a write-protect error will occur.
