 General Comments: 
       The Costeau virus was submitted in January, 1993.  Its origin or 
       point of isolation is unknown.  Costeau is a memory resident infector 
       of .EXE programs. 
       When the first Costeau infected program is executed, the Costeau 
       virus will install itself memory resident in the DOS Data area in 
       memory, hooking interrupt 21.  Total system and available free 
       memory, as indicated by the DOS CHKDSK program, will not be altered. 
       Once the Costeau virus is memory resident, it will infect .EXE 
       programs when they are executed.  Infected programs will have a file 
       length increase of 512 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 
       can be found within the viral code in all Costeau infected programs: 
       It is unknown what Costeau may do besides replicate.
