 General Comments: 
       The Beta virus was received in December, 1991.  Its origin is 
       unknown.  Beta is a non-resident, direct action infector of .COM 
       programs.  It does not infect COMMAND.COM. 
       When a Beta virus infected program is executed, the Beta virus will 
       infect up to three .COM programs located in the current directory. 
       Infected .COM programs will have a file length increase of 1,117 
       bytes.  The virus will be located at the end of the infected file. 
       There will be no change to the file's date and time in the DOS 
       disk directory listing.  No text strings are visible within the 
       viral code in infected files. 
       It is unknown if Beta does anything besides replicate.
