Which description defines a Trojan Horse Virus?

Which description defines a Trojan Horse Virus?

• A. A program that claims to rid your computer of viruses but instead introduces viruses onto your computer
• B. A program that copies itself repeatedly
• C. A Cloud Storage
• D. A USB Flash Drive

Answer: (A)

Trojan horse malware relies on deception, disguising itself as legitimate software to trick you into running it. When you install something that seems helpful—like a tool that promises to remove viruses—you may actually be installing a malicious program. Once active, it can install other malware, create backdoors, or steal data, all while you think you’re running a harmless utility. This description matches because it describes a program that pretends to help and ends up introducing harm. It’s not about self-replication like a worm, nor about a legitimate cloud storage service, nor merely a USB drive as a physical carrier.
