 General Comments: 
       The 702 virus was submitted in July, 1992.  This virus' origin or 
       point of isolation is unknown.  702 is a memory resident infector 
       of .COM programs, though it is somewhat picky about what it will 
       The first time a program infected with the 702 virus is executed, 
       this virus will install itself memory resident as a low system 
       memory TSR of 944 bytes.  Interrupt 21 will be hooked by the virus 
       in memory. 
       Once the 702 virus is memory resident, it may infect .COM programs 
       when they are executed.  Infected programs will have a file length 
       increase of 702 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.  No text strings are visible within 
       the 702 viral code in infected programs. 
       It is unknown if 702 does anything besides replicate.
