CompTIA A+ Core 2 (220-1202)SecurityMedium
A user reports that their web browser is displaying excessive pop-up ads, redirecting to unfamiliar search engines, and changing the homepage without permission. Additionally, the system feels sluggish. The user denies intentionally installing any new software. Which type of malware is MOST likely affecting the system?
- ARansomware
- BRootkit
- CSpyware
- DAdware
Show answer & explanationAnswer & explanation
Correct answer: D. Adware
Adware is specifically designed to display unwanted advertisements, redirect web traffic, and modify browser settings, often leading to system sluggishness due to its resource consumption.
Why the other options are wrong
- A. Ransomware encrypts files and demands payment, which is not described here.
- B. Rootkits hide their presence and often other malware, but don't typically manifest with pop-up ads or redirects as primary symptoms.
- C. Spyware collects user information; while it can cause sluggishness, its primary goal isn't displaying ads or browser hijacking.
Adware
Software that automatically displays or downloads unwanted advertisements when a user is online, often bundled with legitimate software.
- Generates revenue for its creator through advertising.
- Can hijack browser settings (homepage, search engine).
- Often causes system slowdowns and pop-up windows.
Memory trick: Ads mean adware, ransom means ransomware, spying means spyware.
