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:
It is unknown what Filename may do besides replicate.
