 General Comments: 
       The Experiments, or Experiments-755, virus was submitted in 
       February, 1993.  It is from the USSR.  Experiments is a non-resident 
       direct action infector of .EXE programs. 
       When a program infected with the Experiments virus is executed, the 
       Experiments virus will infect all of the .EXE files located in the 
       current directory, though it will not infect very small .EXE files. 
       Infected programs will have a file length increase of 755 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.  The 
       following text string can be found within the viral code in all 
       Experiments infected programs: 
               "---- Small experiments path 2.1 ----" 
       It is unknown what Experiments may do besides replicate.
