CompTIA A+ Core 2 (220-1102) — Question 597

A user receives a message on a PC stating it has been infected by malware. A technician runs a full scan on the user's machine and detects no malware. Later that day, the same message reappears. Which of the following steps should the technician take to restore the system to regular functionality?

Answer options

• A. Check for Windows updates.
• B. Reimage the computer.
• C. Enable Windows Firewall.
• D. Run System File Checker.

Correct answer: B

Explanation

Reimaging the computer is the most effective solution in this scenario as it restores the system to a clean state, eliminating any persistent malware or issues that may not have been detected during the scan. The other options, while potentially helpful for different issues, do not directly address the reoccurring malware notification and may not resolve the underlying problem.
