A user reports that their web browser is redirecting them to unfamiliar search engines and displaying an excessive number of pop-up advertisements. The user also notes that their homepage has changed without their consent. Which type of malware has most likely infected the user's system?
- AKeylogger
- BRansomware
- CAdware
- DRootkit
Show answer & explanationAnswer & explanation
Correct answer: C. Adware
Adware is designed to display unwanted advertisements, often through pop-ups, and can modify browser settings like the homepage or search engine without user permission. The symptoms described directly align with adware behavior.
Why the other options are wrong
- A. Keyloggers record keystrokes, which is not indicated by the user's observed issues.
- B. Ransomware encrypts files and demands payment, which is not indicated by the symptoms.
- D. Rootkits hide malicious processes and maintain access, but don't typically cause excessive pop-ups or browser redirects as their primary symptom.
Adware
Software that automatically displays or downloads unwanted advertisements when a user is online, often bundled with legitimate programs. It can also modify browser settings.
- Displays unwanted pop-up ads
- Can change browser homepage or search engine

Memory trick: Ad-ware bombards you with ads, while ransom holds your data hostage.
