At the present time, FiOS does not impose any hidden bandwidth caps, etc. However, the Verizon ToS stills stands. Also, using excessive net traffic may alert Verizon and monitor your line for somewhat "suspicious" activity.
As you may very well know, Trojan Horses, etc. that infect your machine can cause more damage "behind the scenes", which can in result use your net traffic for malicious content and acts.
If you believe there's any type of security intrusion on your computer(s), it's recommended your machine receives proper care immediately.
