A user's web browser is consistently redirecting to a specific, unwanted search engine whenever they open a new tab or attempt a search. The user has already reset the browser's homepage and default search engine settings multiple times, but the issue persists. Which type of malware is MOST likely causing this behavior?
- ABrowser hijacker
- BWorm
- CRootkit
- DRansomware
Show answer & explanationAnswer & explanation
Correct answer: A. Browser hijacker
A browser hijacker is a type of malware that modifies a web browser's settings without the user's permission, often changing the homepage, default search engine, or redirecting to unwanted sites, and is notoriously difficult to remove through simple browser settings.
Why the other options are wrong
- B. A worm is a self-replicating malware that spreads across networks, not typically focused on browser settings.
- C. A rootkit hides malicious software but doesn't directly cause browser redirection as its primary symptom.
- D. Ransomware encrypts files and demands payment, which is unrelated to browser redirection.
