Explanation

A botnet infection causes the compromised computer to be controlled remotely and used for tasks like sending spam, launching DDoS attacks, or mining cryptocurrency-explaining both the 100% CPU usage and the high outgoing network traffic. A keylogger primarily captures keystrokes with minimal network traffic. Receiving a DDoS attack would produce high incoming-not outgoing-traffic. A software firewall blocking traffic would not cause high CPU or generate outgoing traffic.
