Security Fundamentals — Question 16

You suspect a user's computer is infected by a virus.
What should you do first?

Answer options

• A. Restart the computer in safe mode
• B. Replace the computer's hard disk drive
• C. Disconnect the computer from the network
• D. Install antivirus software on the computer

Correct answer: D

Explanation

The correct answer is D because installing antivirus software is crucial for detecting and removing any potential virus. Restarting in safe mode (A) can be helpful later, but the first step should be to ensure antivirus protection. Replacing the hard disk drive (B) is unnecessary and drastic, while disconnecting from the network (C) does not address the virus issue directly.
