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?
- ARansomware
- BAdware

Show answer & explanationAnswer & 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.
