CompTIA A+ Core 2 (220-1102) — Question 574

A user's workstation was infected with a newly discovered virus that the AV system detected. After a full virus scan and a workstation reboot, the virus is still present in the OS. Which of the following actions should the user take to remove the virus?

Answer options

• A. Enable the system firewall.
• B. Use bootable antivirus media to scan the system.
• C. Download software designed to specifically target the virus.
• D. Run the operating system update process.

Correct answer: B

Explanation

Using bootable antivirus media is effective because it operates outside the infected operating system, allowing it to detect and remove malware that may be actively hiding during a standard scan. The other options, such as enabling the firewall or updating the OS, do not directly address the existing virus. Downloading software may also be ineffective if the virus prevents installations or modifications in the system.
