 General Comments: 
       The Antimon virus was received in November, 1991.  Its origin is 
       unknown.  Antimon is a non-resident, direct action infector of 
       .COM files, including COMMAND.COM. 
       When a program infected with Antimon is executed, the Antimon virus 
       will infect all previously uninfected .COM files located in the C: 
       drive root directory.  Since COMMAND.COM normally resides in this 
       directory, it will be infected as well. 
       Antimon infected files increase in size by 1,452 to 1,465 bytes. 
       The virus will be located at the end of all infected files. 
       There will be no change in the file's date and time in a DOS disk 
       directory listing. 
       The following text strings will be found within the viral code of 
       Antimon infected programs: 
               "= C:\PDPROG" 
       It is unknown what Antimon does besides replicate.
