 General Comments: 
       The StarDot 789 virus was submitted in September, 1991.  Its origin 
       is unknown.  StarDot 789 is a non-resident, direct-action infector 
       of .COM and .EXE files, including COMMAND.COM. 
       When a program infected with StarDot 789 is executed, this virus 
       will search the current directory for an uninfected .EXE file to 
       infect.  If one is found, it will be infected.  If an uninfected 
       .EXE file is not found, the virus will then search the current 
       directory for an uninfected .COM program to infect, and infect 
       it if found. 
       StarDot 789 infected files will have a file size increase of 789 
       to 805 bytes with the virus being located at the end of the 
       infected file.  There will be no change in the file's date and 
       time in the DOS disk directory. 
       Systems infected with StarDot 789 may experience system hangs 
       when the user attempts to execute infected .COM files. 
       It is unknown what StarDot 789 does besides replicate.
