What is the technical difference between a worm and a virus?
As I understand it, a worm actively seeks out new victims (or attempts to send itself to new victims) once it has infected a host. A virus won’t do this, if my understanding is correct.
Actually, a virus replicates itself by inserting itself into other programs, so that when that program is opened the infection spreads.
A worm, on the other hand, is a self-contained program. Once executed, it replicates by sending out copies of itself, but it does not insert itself into other code.
