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"
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.
