What best describes a Trojan Horse program?

A Trojan Horse program is best described as a malicious program that disguises itself as legitimate software. This type of malware often tricks users into downloading and executing it by appearing to be something useful or innocuous, such as a software application, a game, or a utility. Once activated, however, a Trojan can carry out various harmful actions without the user's knowledge, which may include stealing sensitive information, creating backdoors for other malware to exploit, or causing damage to the system.

The essence of a Trojan Horse lies in its deceptive nature. Users are often unaware of the program's true intent because it masquerades as trustworthy, leading to potential compromises in security. Understanding this concept is crucial in cybersecurity, as awareness of how Trojans operate helps users implement better security measures, such as verifying the sources of software downloads and being cautious about installing unfamiliar programs.
