 General Comments: 
       The Filename virus was submitted in June, 1993.  Its origin or 
       point of isolation is unknown.  Filename is a non-resident, direct 
       action infector of .COM files, but not COMMAND.COM.  It also does 
       not infect very small .COM files. 
       When a program infected with the Filename virus is executed, this 
       virus will infect one .COM program located in the current directory. 
       Infected programs will have a file length increase of 512 bytes with 
       the virus being located at the beginning of the program.  The file's 
       date and time in the DOS disk directory listing will not appear to 
       have been altered, though the seconds field will have been set to 
       "42".  The following text string is visible within the viral code in 
       all Filename infected programs: 
               "*.COM V" 
       It is unknown what Filename may do besides replicate.
