Explanation

A worm is self-replicating malware that spreads without user interaction, commonly by harvesting and mailing itself to all contacts in a victim's address book. The key indicators here are multiple machines being compromised and the malware automatically propagating via email contact lists. A Trojan disguises itself as legitimate software but doesn't self-replicate. A logic bomb is a dormant payload triggered by a specific condition. A botnet involves a command-and-control infrastructure directing compromised machines - the question doesn't indicate external C2 control, just self-spreading behavior.
