Which type of malware is designed to display unsolicited advertisements to the user?

• A. Rogueware
• B. Adware
• C. Spyware
• D. Trojan

Answer: (B)

Adware is software whose main purpose is to display unsolicited advertisements to the user. It typically shows pop-ups, banners, or forced ads within applications or on the desktop, often bundled with free or legitimate-looking software. The ads generate revenue for the attacker and can appear regardless of user intent, sometimes slowing the system or invading privacy by tracking usage to tailor ads. This behavior distinguishes it from other types of malware: scareware (rogueware) tries to frighten you into paying for fake fixes; spyware covertly collects information about your activity; and a Trojan hides malicious code inside a legitimate-looking program. So, the defining feature here is the explicit display of ads to the user, which is what identifies this malware type.
