Question

malware that captures information from a computer without the users knowledge or consent is
a. a virus
b. a worm
c. adware
d. spyware

Explanation:

• A virus requires a host file to spread and typically damages or corrupts data, not mainly for capturing info without consent.
• A worm spreads independently across networks but is more about replicating and spreading, not focused on stealthy info capture.
• Adware is mainly for displaying ads, often with user awareness (even if unwanted), not for capturing info secretly.
• Spyware is specifically designed to collect user information (like keystrokes, browsing data) without the user's knowledge or consent.
