What is a file infector?
A file infector is a virus that attaches itself to, or is associated with, an executable file. An executable file can be a program file, like Word or Excel, or a system file, like command.com or the Macintosh’s Desktop file or Finder. A file infector spreads when an infected executable file is run; other application files that are run subsequently then become infected. The infection can also spread to executable files, which are run from writable floppies on an infected computer. The infection is usually spread to other computers by sharing infected executables.
