 General Comments: 
       The LoveChild-2710 virus was submitted in March, 1993.  Its origin 
       or point of isolation is unknown.  LoveChild-2710 is a memory 
       resident stealth virus which infects .COM programs, including 
       When the first LoveChild-2710 infected program is executed, this 
       virus will install itself memory resident at the top of system 
       memory but below the 640K DOS boundary, hooking interrupts 13 and 
       24.  Total system and available free memory, as indicated by the 
       DOS CHKDSK program, will have decreased by 4,096 bytes.  Interrupt 
       12's return will not have been moved.  Also at this time, the virus 
       will infect COMMAND.COM if it was not previously infected. 
       Once memory resident, the LoveChild-2710 virus will infect .COM 
       programs when they are executed or opened for any reason.  Infected 
       programs will have a file length increase of 2,710 bytes, though 
       the file length increase is not visible when the virus is resident 
       in memory.  LoveChild-2710 will be located at the end of infected 
       files.  The program's date and time in the DOS disk directory 
       listing will not be altered.  No text strings are visible within 
       the viral code in infected programs. 
       Systems infected with the LoveChild-2710 virus will find that when 
       the virus is memory resident, the DOS CHKDSK program will indicate 
       file allocation errors on all infected files.
