Continuing my monologue on this topic....
I have now found out how to reproducibly create the AIS FW 'unknown connections'.
Open an application that connects and includes an outbound UDP 'listening' connection (eg PSI).
- AIS FW shows all the connections and the associated application name and PID
- Task Manager shows the PID and application name.
Close the application.
- AIS FW still shows the UDP 'listening' connection and the application name and PID. Other connections disappear.
- Task Manager doesn't show it any more because the application isn't running.
Close avast UI, then reopen it.
- AIS FW still shows the UDP 'listening' connection and the PID - but the name has now become 'unknown'.
You need to have 'Detailed View' ticked to see this.
Now what I need to know is why it happens - and why does it apparently only happen to me, yet happens on both my W7 and my XP systems?
I think it maybe has something to do with the fact that detailed view is also showing historic info - ie data on connections that have closed, and I now suspect (hope) that it is actually no concern at all!
