 General Comments: 
       The MiniMax virus was submitted in February, 1993, and originally 
       is from the USSR.  MiniMax is a non-resident, direct action 
       infector of .COM programs, including COMMAND.COM. 
       When a program infected with the MiniMax virus is executed, the 
       MiniMax virus will infect one .COM program located in the current 
       directory, and then the host program the user was attempting to 
       execute will run.  Programs infected with the MiniMax virus will 
       become 31,125 bytes in length with the virus being located at the 
       end of the file.  The actual MiniMax viral code is quite small, and 
       most of the file length increase will comprise hex C3 characters. 
       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 can be found within the viral 
       MiniMax doesn't appear to do anything besides replicate.
