CompTIA A+ Core 2 (220-1002) — Question 104
Joe, a user, believes his computer is infected with malware. The device is having difficulty accessing some websites, and web services are not responding from any of the web browsers, although Joe can access these services from his smartphone without issue. The computer's malware scanner has the latest definitions installed. Which of the following would BEST explain why the computer is functioning this way?
Answer options
- A. Expired root certificate
- B. OS update failures
- C. Pop-up blocker
- D. Hijacked email
Correct answer: A
Explanation
An expired root certificate can prevent a computer from establishing secure connections to websites, explaining Joe's browsing difficulties. OS update failures, pop-up blockers, and hijacked email do not directly relate to the specific issue of website access that Joe is experiencing.
