Trojan horse malware, commonly known as Trojans, is a type of malicious software designed to mislead users about its true intent. Unlike viruses, Trojans cannot replicate themselves but rely on tricking users into installing them. Once inside a system, Trojans can steal personal information, spy on users, and even give cybercriminals remote access to the infected machine. Named after the ancient Greek story of the deceptive wooden horse, Trojans disguise their harmful functions to appear benign or useful.
