A technician is troubleshooting a PC because the user has reported strange pop-up windows and computer performance issues. Which of the following actions should the technician take next?

Answer options

• A. Isolate the machine from the network.
• B. Scan the system for hidden files.
• C. Disable unused ports.
• D. Install antivirus software.
• E. Reconfigure the firewall.

Correct answer: A

Explanation

Scanning for hidden files, disabling unused ports, installing antivirus software, and reconfiguring the firewall are important steps, but isolating the machine takes priority to contain the issue.
