CompTIA A+ Core 2 (220-1002) — Question 144

A home user reports slow computer performance and application crashes after clicking a `repair` button on a pop-up warning while browsing the Internet. Which of the following are the FIRST steps a technician should take to identify and resolve the issue? (Choose two.)

Answer options

• A. Perform a system file check and replace any changed files with their original versions
• B. Enable the pop-up blocker on the Internet browser
• C. Uninstall any recently installed unknown programs and browser extensions
• D. Perform a hard shutdown and cold boot the computer
• E. Scan the RAM and hard drive using an up-to-date antivirus program

Correct answer: B, C

Explanation

The correct answers, B and C, focus on immediate actions to prevent further issues by blocking unwanted pop-ups and removing suspicious programs. Performing a system file check (A) and scanning for viruses (E) are important but should follow after addressing the immediate concerns. A hard shutdown (D) is a last resort and does not address the underlying problem.
