I've been knocking at this issue for a while, and it may be coming down to reasonably simple answers, at least so before setting off another round of investigation.
Problem: systems tray networking icon and panel indicate, from time to time, a "continuous outbound signal"--packets seem to be going somewhere, but it's harder getting a handle on that.
1. If I don't initiate an online transaction, CURRENT PORTS, my port sniffer, indicates no services engages with a remote IP.
2. The raft of malware detectors--e.g., Defender, Black Ice, Antivir, etc.--have been coming up predominantly clean as regards their systems scans.
This is my question for the day:
a) Could the systems tray network icon, lit continuously on the left side, be indicating the presence of some kind of internal loop within the system? If so, what are the possibilities as regards the false positive state?
On the other hand, is it possible that the network icon is telling the truth--information is leaving my machine--but the signal has been masked from the Current Ports software?
