 General Comments: 
       The End Of virus was submitted in August, 1992.  It is originally 
       from the USSR.  End Of is a memory resident infector of .COM 
       programs, including COMMAND.COM. 
       When the first End Of virus infected program is executed, this 
       virus will install itself memory resident at the top of system 
       memory but below the 640K DOS boundary.  Total system and available 
       free memory will have decreased by 800 bytes, and interrupt 21 will 
       be hooked. 
       Once End Of is memory resident, it will infect .COM programs when 
       a DOS DIR command is issued.  Infected programs will have a file 
       length increase of 783 bytes with the virus being located at the 
       end of the infected file.  The program's date and time in the 
       DOS disk directory listing will not be altered.  The following 
       text strings can be found in the viral code in all End Of infected 
               "end of" 
       It is unknown what End Of may do besides replicate.
