Gatekeeper, by Chris Johnson,
is a program designed to continuously monitor the operation of your Macintosh,
watching for operations that are commonly carried out by viruses as they try
to propagate. When Gatekeeper detects an infection attempt it will automatically
stop the attempt, almost before it's started.
