A user reports that their Windows 10 computer is running extremely slow and frequently displays pop-up ads, even when a web browser is not open. The user also notices new, unfamiliar icons on their desktop. Which type of malware is MOST likely causing these symptoms?
- ASpyware
- BRootkit
- CAdware
- DRansomware
Show answer & explanationAnswer & explanation
Correct answer: C. Adware
Adware is designed to display unwanted advertisements and often installs without explicit user consent, leading to pop-ups and sometimes new desktop icons. Its primary goal is to generate revenue through ads.
Why the other options are wrong
- A. Spyware collects user information silently, but pop-up ads and new icons are more characteristic of adware.
- B. Rootkits hide malicious processes, but do not typically cause pop-up ads or new desktop icons directly.
- D. Ransomware encrypts files and demands payment, which is not described here.
Adware
Software that automatically displays or downloads unwanted advertisements, often bundled with legitimate software, leading to pop-ups and performance issues.
- Displays unsolicited advertisements.
- Can be bundled with free software.
- Often causes system slowdowns and pop-up windows.
Memory trick: Slow computer, annoying ads, new icons: Adware's calling card.
