 General Comments: 
       The Hamster, or Turbo Hamster, virus was submitted in March, 1993. 
       Its origin or point of isolation is unknown, though it was provided 
       by an individual in North America.  Hamster is a non-resident, 
       direct action infector of .COM programs, including COMMAND.COM. 
       When a program infected with the Hamster virus is executed, the 
       Hamster virus will infect one program in the current or a higher 
       directory.  Infected programs will have a file length increase of 
       546 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 
       usually not be altered, though in the case of COMMAND.COM, it may 
       become altered to a date in the future.  The following text strings 
       are visible within the viral code in all Hamster infected programs: 
               "Turbo Hamster Virus!" 
       It is unknown what Hamster may do besides replicate.
