 General Comments: 
       The Green Joker, or Green, virus was submitted in June, 1992.  Its 
       origin or point of isolation is unknown.  Green Joker is a non- 
       resident, direct action infector of .COM programs, including 
       COMMAND.COM.  It may be related to the Ash virus. 
       When a program infected with the Green Joker virus is executed, this 
       virus will infect all of the .COM programs located in the current 
       directory.  If COMMAND.COM is located in this directory, it will 
       become infected.  Programs infected with the Green Joker virus will 
       have a file length increase of 743 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 have been updated to the current 
       system date and time when infection occurred. 
       The Green Joker virus will usually display a message on the system 
       display when an infected program is executed.  Occassionally, the 
       message will be accompanied by beeping on the system speaker.  The 
       messages which may be displayed by the virus are: 
              "Fail on INT 24" 
              "Impotence error reading user's dick 
               Abort, Retry, Ignore, Fail?" 
              "Program too big to fit in memory" 
              "Cannot load COMMAND, system halted" 
       The above message text strings can be found within the viral code 
       in infected programs, along with the following two additional text
