CompTIA A+ Core 2 (220-1002) — Question 184

A user can access the company's internal website properly, but some e-commerce websites have stopped loading and been replaced with an error message. The technician who is troubleshooting the issue tries to update the malware scanner over the network, but the automatic update fails. However, a manual update is successful from a USB drive. No viruses are detected on the device after a full system scan.
Which of the following is the MOST likely cause of the issue?

Answer options

• A. Incorrect time
• B. Browser redirection
• C. Hijacked email
• D. Rogue antivirus

Correct answer: A

Explanation

The most likely cause of the issue is 'Incorrect time' because many websites require accurate timestamps for secure connections, which can lead to loading errors if the system time is wrong. Options like 'Browser redirection' and 'Hijacked email' do not explain the successful USB update and lack of detected viruses, while 'Rogue antivirus' does not fit since no malware was found.
