Which type of malware can self-replicate and propagate without needing a host program?

Correct option is B

A Worm is a type of malware that can self-replicate and propagate across networks without the need for a host program. Worms spread by exploiting vulnerabilities in network systems and can cause widespread disruption by consuming bandwidth and overloading systems.
Important Key Points:
1. Worms can replicate independently and spread across networks, making them highly contagious.
2. They do not require a host file or program to execute and spread, unlike viruses.
Knowledge Booster:
· Virus: A virus needs a host file or program to replicate and spread. It infects files and requires user action to spread.
· Trojan Horse: Trojans disguise themselves as legitimate software but do not replicate or spread on their own.
· Spyware: Spyware monitors user activities without self-replication capabilities.
· Ransomware: Ransomware encrypts files and demands payment for decryption but does not self-replicate without assistance.
