 General Comments: 
       The Interceptor virus was received in September, 1991, and is 
       originally from Milan, Italy.  Interceptor is based on the Vienna 
       virus, and like Vienna, is a non-resident infector of .COM 
       programs, including COMMAND.COM. 
       When a program infected with Interceptor is executed, Interceptor 
       will search the current directory to locate the first two uninfected 
       .COM files.  These two files will then be infected.  If an 
       uninfected COMMAND.COM program is found as one of the first two 
       uninfected .COM files, it will be infected. 
       Programs infected with Interceptor will increase in size by 1,014 
       bytes.  Interceptor will be located at the end of the infected 
       programs.  The following text strings can be found near the end 
       of all infected files: 
               "Interceptor - by Cracker Jack 1991 IVRL Milan, Italy" 
       It is unknown if Interceptor does anything besides replicate.  This 
       virus appears to be a research virus at the time of its original 
       See:   Vienna
