A virus, worm, and Trojan horse are all types of malicious software (malware) designed to harm or exploit systems, but they differ in how they spread and function.

1. Virus: A virus is a type of malware that attaches itself to a legitimate program or file. It spreads when the infected program or file is executed or opened, often requiring user interaction. Once active, it can replicate itself, potentially corrupting files, stealing information, or causing system crashes. Viruses often rely on human actions (e.g., opening an email attachment or downloading an infected file) to spread.

2. Worm: A worm is a self-replicating piece of malware that does not require a host program to spread. It exploits vulnerabilities in software or operating systems to propagate across networks or devices. Worms can spread without any user intervention, making them more dangerous than viruses. They can slow down or crash networks, steal data, and sometimes cause denial-of-service (DoS) attacks by overwhelming systems with traffic.

3. Trojan Horse: A Trojan horse, or Trojan, disguises itself as a legitimate or harmless program to trick users into downloading or executing it. Unlike viruses and worms, Trojans do not replicate themselves or spread automatically. Instead, they rely on deception, often posing as useful software (e.g., games, utilities). Once activated, they can give attackers access to the infected system, steal sensitive data, or install additional malware.

In summary:

• Virus: Requires a host and user interaction to spread.

• Worm: Self-replicates and spreads autonomously, often via networks.

• Trojan horse: Disguises itself as legitimate software to trick users into installation.
