Which type of malware is known for its ability to disguise itself during installation?

The chosen answer represents a type of malware known as a Trojan, which is designed to appear legitimate or innocuous in order to deceive users into installing it. Trojans often masquerade as useful applications or files, compelling users to download and run them under the guise of performing useful functions. Once installed, the Trojan can carry out malicious activities, such as stealing personal information, providing unauthorized access to systems, or downloading additional malicious software, all while maintaining the appearance of a harmless program.

This characteristic of disguise is a critical component of why Trojans can be particularly effective in infecting systems. Users are often unaware of the dangers they are introducing to their devices because they trust the source or the function of the application they are installing. Understanding this behavior helps with effective security practice, as user awareness and vigilance are essential for preventing Trojan infections.
