Question:
What type of malware has the primary objective of spreading across the network?

• worm
• virus
• Trojan horse
• botnet

Explanation: The main purpose of a worm is to self-replicate and propagate across the network. A virus is a type of malicious software that needs a user to spread. A trojan horse is not self-replicating and disguises itself as a legitimate application when it is not. A botnet is a series of zombie computers working together to wage a network attack.
