Correct Answer

Option 2: Keyloggers

Keystroke Logging: A keylogger (short for keystroke logger) is a specific type of surveillance software or hardware designed to record every single key pressed on a computer keyboard.

The Goal: Because it captures everything silently in the background, it easily steals highly sensitive information as you type it—including usernames, passwords, credit card numbers, and personal messages—before sending that data back to an attacker.

Why the Other Options Are Incorrect

Option 1: Virus

Function: A type of malware that attaches itself to a legitimate program and replicates to spread across files and systems, often corrupting or deleting data.

Why it's wrong: While dangerous, a standard virus is defined by how it spreads and replicates, not by tracking specific keyboard inputs.

Option 3: Worms

Function: Standalone malware that self-replicates across computer networks automatically, exploiting security vulnerabilities to slow down networks or consume bandwidth.

Why it's wrong: Worms focus on spreading rapidly through systems without human interaction; they do not explicitly record keystrokes.

Option 4: Ransomware

Function: A specific type of extortion malware that encrypts a user's files or locks their system, demanding a cryptocurrency ransom payment in exchange for the decryption key.

Why it's wrong: Ransomware holds your data hostage for money; it does not quietly log your typing activities.
