CompTIA A+ Core 2 (220-1002) — Question 347

Which of the following malware types would MOST likely require reimaging?

Answer options

• A. Botnet
• B. Spyware
• C. Rootkit
• D. Keylogger

Correct answer: C

Explanation

A rootkit operates at a low level within the system, making it difficult to detect and remove without erasing the entire system. In contrast, botnets, spyware, and keyloggers can often be removed through antivirus software or other security measures without requiring a complete reimaging of the system.
