Question
When users turn on or reboot their machines, many of the computers on the network are non- responsive and unable to access the Internet. The users who left their computers on or have not rebooted are not experiencing this issue. A technician confirms all the network switches and routers are working, and no servers are having any issues. The network administrator notices abnormally high network utilization. Which of the following is the MOST likely issue the company is experiencing?
Options
- AMalware infection
- BRogue antivirus

Explanation
The pattern here strongly indicates a malware infection: only rebooted machines are affected (malware activates on boot), machines left on are unaffected (malware not yet triggered or already suppressed), network infrastructure is confirmed healthy, and there is abnormally high network utilization (malware often communicates outbound - beaconing to C2 servers, spreading to other hosts, or exfiltrating data). Rogue antivirus (B) typically involves fake security popups, not startup-triggered network floods. Browser redirection (C) requires browser activity. OS update failures (D) would not cause high network utilization across rebooted machines simultaneously.
