    The other way around, rob. Although they both self-replicate. A virus needs a host program. The worm doesn't.
    The programmer’s wife tells him: “Run to the store and pick up a loaf of bread. If they have eggs, get a dozen.”
    The programmer comes home with 12 loaves of bread.

    There's this issue in which a worm carries a payload that tries to do more than just simply spreading the worm over the network; corrupting files, planting backdoors, etc... It can be confused by a virus on this instance, or even a trojan... arguably.

    It's still a worm though if the replication code targets the network. Where's a virus replication code targets the computer memory.
