CompTIA A+ Core 2 (220-1102) — Question 321

A workstation is displaying a message indicating that a user must exchange cryptocurrency for a decryption key. Which of the following is the best way for a technician to return the device to service safely?

Answer options

Correct answer: B

Explanation

Reinstalling the operating system is the most effective approach to ensure that any malware or ransomware is completely removed from the device. Running an AV scan may not detect all forms of ransomware, while installing a software firewall or performing a system restore does not guarantee the removal of the infection. Complying with the on-screen instructions could lead to further compromise of the system.
