CompTIA A+ Core 2 (220-1002) — Question 255

A user's antivirus recently expired, so the user downloaded and installed a free system protection application. The application found numerous rootkits, Trojans, viruses, and missing critical patches. It was unable to fix all the issues, however, and suggested the user call technical support. Which of the following is the FIRST step to begin repairing the computer?

Answer options

• A. Remove the rogue antivirus.
• B. Install Windows Updates.
• C. Reimage the computer.
• D. Call the technical support number.

Correct answer: B

Explanation

The first step should be to install Windows Updates, as this can address critical vulnerabilities and patch the system. Removing the rogue antivirus or contacting support might be necessary later, but updating the system helps secure it against existing threats. Reimaging the computer could be a last resort if other methods fail, but it's not the immediate step to take.
