 General Comments: 
       The Smaug virus was submitted in September, 1993.  Its origin or 
       point of isolation is unknown.  Smaug is a non-resident, direct 
       action infector of .COM programs, but not COMMAND.COM. 
 
       When a program infected with the Smaug virus is executed, this 
       virus will infect one .COM program located in the current directory. 
       Infected programs will have a file length increase of 349 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 Smaug 
       infected programs: 
 
               "COMMAND.*.COM" 
               "I$ WRD MIG" 
               "$MG IV$"
