A user reports that their Windows 10 computer is displaying frequent pop-up advertisements, even when no browser is open. The advertisements often appear in the bottom-right corner of the screen and sometimes include notifications for fake security warnings. Which type of unwanted software is most likely causing this issue?
- AAdware
- BRansomware
- CKeylogger
- DRootkit
Show answer & explanationAnswer & explanation
Correct answer: A. Adware
Adware is designed to display unwanted advertisements, often through pop-ups or notifications, even when a web browser is not actively in use. Ransomware encrypts files, rootkits hide malicious processes, and keyloggers record keystrokes.
Why the other options are wrong
- B. Ransomware encrypts user files and demands payment, which does not align with the symptoms described.
- C. A keylogger records user keystrokes and does not typically manifest as pop-up advertisements.
- D. A rootkit is designed to gain unauthorized control and hide its presence, not primarily to display ads.

Memory trick: Adware is for Ads, Ransomware demands a Ransom, Rootkits hide, Keyloggers log keys.
