CompTIA ITF+ (FC0-U71) — Question 20

Which of the following can best protect a computer when an infected file has been downloaded?

Answer options

• A. Anti-malware
• B. Firewall
• C. Patching
• D. Permissions

Correct answer: A

Explanation

Anti-malware software is specifically designed to detect and remove malicious files from a computer, making it the best option for protection after an infected file is downloaded. A firewall primarily controls network traffic, while patching addresses vulnerabilities in software, and permissions manage user access, none of which directly remove malware from a system.
