 General Comments: 
       The Italian Boy virus was submitted in April, 1993, and is from 
       Italy.  Italian Boy is a memory resident infector of .COM programs, 
       including COMMAND.COM.  It is a destructive virus. 
       When the first Italian Boy virus is executed, the Italian Boy virus 
       will install itself memory resident at the top of system memory but 
       below the 640K DOS boundary, not moving interrupt 12's return.  Total 
       system and available free memory, as indicated by the DOS CHKDSK 
       program, will have decreased by 896 bytes. 
       Once the Italian Boy virus is memory resident, it will infect .COM 
       programs when they are executed.  Infected .COM programs will have a 
       file length increase of 578 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 strings 
       are visible within the viral code in all Italian Boy infected files: 
               "Fucks to Italian Virus Killers" 
       The Italian Boy virus activates when it becomes memory resident on 
       or after April 3rd of any year.  At that time, the virus will draw 
       an Italian flag on the system display, along with the above text 
       message, and may trash the system hard disk.
