 General Comments: 
       The Shizu virus was received in February, 1995.  Its origin or point 
       of isolation is unknown.  Shizu is a non-resident, direct action 
       infector of .COM files, including COMMAND.COM. 
       When a program infected with the Shizu virus is executed, this virus 
       will infect the first uninfected .COM file located in the current 
       directory.  Programs infected with the Shizu virus will have a file 
       length increase of 568 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 
       can be found starting in the fifth byte of all infected files: 
       The following text strings are encrypted within the viral code: 
               "--- Be careful VIRUS !!! ---" 
       Once the Shizu virus has infected all of the .COM files in the 
       current drive current directory, it may access other drives to 
       locate programs to infect.
