I'm on Mac OS 10.13. got this warning on my router:

Threat A Network Trojan was Detected. Signature ET MALWARE Suspicious User Agent (Autoupdate). From:, to:, protocol: TCP

I did "% lsof -i" to try to figure out which process it was, but none was using that port when I checked. Is there any way to monitor the port continuously and catch which process tries to use it, the next time it does?
