CompTIA A+ Core 2 (220-1202)SecurityMedium

A user reports that their web browser is displaying excessive pop-up ads, redirecting to unwanted sites, and their homepage has been changed without their consent. The user also mentions that they recently downloaded a free utility program from a non-official website. What type of malware is MOST likely causing these issues?

  1. ARansomware
  2. BAdware
  3. CSpyware
  4. DTrojan
Show answer & explanation

Correct answer: B. Adware

The symptoms described—excessive pop-ups, browser redirects, and homepage changes—are classic indicators of adware. Adware is specifically designed to display unwanted advertisements and often comes bundled with other software.

Why the other options are wrong

  • A. Ransomware encrypts data and demands payment for its release.
  • C. Spyware secretly collects user information without their knowledge.
  • D. A Trojan disguises itself as legitimate software to gain access, but its primary function isn't usually just showing ads.

Adware

Software that automatically displays unwanted advertisements, often bundled with other programs.

  • Generates revenue for its creator through ads.
  • Can change browser settings like homepage or search engine.
  • Often installed without explicit user consent, sometimes alongside legitimate software.
