 General Comments: 
       The Pirate 1344 virus was received in October, 1993.  Its origin or 
       point of isolation is unknown.  Pirate 1344 is a memory resident 
       infector of .EXE programs. 
       When the first Pirate 1344 infected program is executed, this 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 1,344 bytes.  Interrupts 09 
       and 21 will be hooked by the virus in memory. 
       Once the Pirate 1344 virus is memory resident, it will infect .EXE 
       programs when they are executed.  Infected programs will have a 
       file length increase of 1,344 to 1,358 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 
       string is visible within the viral code in all Pirate 1344 infected 
       Characters from system memory may occassionally be displayed on the 
       system monitor on infected monochrome systems.  Execution of some 
       programs may fail with the following message: 
               "Program too big to fit in memory" 
       Pirate 1344 does not appear to be related to the  Pirate  virus 
       described in another entry.
