  -----------------


  The following is the conclusion on the nature of bljec viruses from

  version 3-9:


  All version are infected file *.com in the current directory, the

  viruses only replicate and increase the size of the infected file.

  No other things are done.


  Version 3 replicate and infects *.com in current directory virus id

  9090


  Version 4 modified version of ver 3 not reinfect infected files.


  Version 5 modified version 4, nothing have noticed different from

  ver 4


  Version 6 not infect COMMAND.COM


  Version 7 infects only 3 files in current directory


  Version 8 modified the date of the infected file


  Version 9 modified ver of 8, some bugs are fixed, I thinks


  Origin: USSR
