 General Comments: 
       The Exunt virus was received in July, 1992.  Its origin or point 
       of isolation is unknown.  Exunt is a non-resident direct action 
       infector of .COM programs, though it does not infect all .COM 
       When a program infected with the Exunt virus is executed, the 
       Exunt virus may infect one .COM program located in the current 
       directory.  Infected programs will have a file length increase 
       of 148 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 have been updated to the current system date and 
       time.  The only text string visible within the Exunt viral code 
       in infected programs is: 
       Exunt doesn't do anything besides replicate.
