 General Comments: 
       The Little-139 virus was submitted in March, 1993, with documentation 
       indicating that it was written for the "First International Virus 
       Writing Contest 1993" sponsored by American Eagle Publications, Inc. 
       It was submitted with original source code, and is a simple, non- 
       resident, direct action .COM infector. 
       When a program infected with the Little-139 virus is executed, this 
       virus will infect one .COM program located in the current directory. 
       Infected programs will have a file length increase of 139 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 following text string is visible within the viral code: 
               "*.COM 3" 
       Little-139 doesn't do anything besides replicate.
