List different types of malicious codes and describe their features?

Answer 1

Malicious code encompasses various types of threats, including viruses, worms, Trojans, ransomware, and spyware. Viruses attach themselves to legitimate files and spread when those files are executed, while worms replicate independently across networks without user intervention. Trojans disguise themselves as legitimate software to trick users into installation, and ransomware encrypts files, demanding payment for decryption. Spyware covertly monitors user activities and collects sensitive information, often leading to identity theft.
