 General Comments: 
       The SeaCat virus was submitted in December, 1992.  Its origin or 
       point of isolation is unknown.  SeaCat is a non-resident, direct 
       action infector of .COM programs, including COMMAND.COM. 
       When a program infected with the SeaCat virus is executed, the 
       SeaCat virus will infect one .COM program located in the current 
       directory.  Infected programs will have a file length increase of 
       160 bytes with the virus being located at the beginning of the 
       file.  The program's date and time in the DOS disk directory listing 
       will have been updated to the current system date and time when 
       infection occurred.  The Read-Only attribute will be set on in the 
       DOS disk directory listing for the file.  The following text string 
       can be found within the viral code in all SeaCat infected programs: 
       SeaCat will corrupt .COM programs smaller than 160 bytes when they 
       are infected by the virus.
