Virtual Keyboards protect the computer against
Answer: D
Virtual keyboards protect against all three, so the answer is All of the above.
A virtual (on-screen) keyboard lets the user enter text, such as a password, by clicking keys with the mouse rather than pressing physical keys. Keyloggers, which are often delivered by Trojan programs or are a form of spyware, record keystrokes, so they cannot capture input that is never typed.
This is why banking sites offer virtual keyboards for passwords: they guard against password theft, Trojans and spyware that log keys. Choosing any one alone would be incomplete.
