Detailed

The technician should disconnect the computer from the network (Option A) first to prevent any further spread of the infection or data loss. Once the machine is isolated from the network, the technician can safely investigate the malware without risking infection to other systems.

Running an antivirus scan (Option B) comes after isolating the system.

Rebooting the computer (Option C) could lead to the loss of critical information or make it harder to diagnose the issue.

Educating the user (Option D) is important but should happen after resolving the immediate issue.
