A, B
Explanation:
• Trojan horse: A Trojan horse is a program that appears to be a useful application, but might capture a user's password and then make it available to the attacker.
• Keylogger: A program that runs in a computer's background and it logs keystrokes that a user makes. Therefore, after a user enters a password, the password is stored in the log created by the keylogger. An attacker can then retrieve the log of keystrokes to determine the user's password.
