       from the USSR.  Press is a non-resident, direct action infector of 
       .EXE programs. 
       When a Press infected program is executed, the Press virus will 
       infect one .EXE program located in the current directory.  Infected 
       programs will have a file length increase of 1,024 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 strings are visible within the viral code in all 
       Press infected programs:

               "Press any key" 
               "\ IRUS S"
