 General Comments: 
       The Poet Code virus was received in July, 1993.  Its origin or 
       point of isolation is unknown.  Poet Code is a memory resident 
       infector of .COM and .EXE programs, including COMMAND.COM. 
       When the first Poet Code infected program is executed, the Poet 
       Code virus will install itself memory resident at the top of system 
       memory but below the 640K DOS boundary, not moving interrupt 12's 
       return.  Total system and available free memory, as indicated by the 
       DOS CHKDSK program, will have decreased by approximately 3K. 
       Interrupts 03 and 21 will be hooked by the Poet Code virus in memory. 
       Once the Poet Code virus is memory resident, it will infect .COM and 
       .EXE programs, including COMMAND.COM, when they are executed. 
       Infected programs will have a file length increase of 2,149 to 2,224 
       bytes with the virus being located at the end of the file.  The 
       program's date and time in the DOS disk directory listing will not 
       be altered.  The following text strings are encrypted within the 
       Poet Code virus, and are thus not visible within infected programs: 
               "Lucifer Messiah -- ANARKICK SYSTEMS" 
               "POET Prototype" 
       Programs infected with the Poet Code virus will frequently hang the 
       system when they are executed.  Additionally, a low pitched sound 
       or beep may be emitted from the system speaker, followed by a 
       continuous buzzing sound.
