 General Comments: 
       The Satana or Satana.665 virus was received in January, 1996.  Its 
       origin or point of isolation is unknown.  Satana is a memory 
       resident fast infector of .COM and .EXE files, including COMMAND.COM. 
       When the first Satana infected program is executed, this virus will 
       install itself memory resident at the top of system memory but 
       below the 640K DOS boundary, not moving interrupt 12's return. 
       Available free memory, as indicated by the DOS CHKDSK program from 
       DOS 5.0, will have decreased by 688 bytes.  Interrupt 21 will be 
       hooked by the virus in memory. 
       Once the Satana virus is memory resident, it will infect .COM and 
       .EXE files when they are executed or opened, but not when copied. 
       Infected files will have a file length increase of 665 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 appear to be 
       altered, though the seconds field will have been set to "62".  The 
       following text string is visible within the viral code: 
           "SATANA 666 (C) EA inc."
