Firewall network connections

Hi,

Just after a bit of advice please. just started using trial internet security feature and when I have been looking through the various features noticed that on the Network Connections screen lots of different connections from various parts of the world being showed as established/listening etc.
Is this a cause for concern? does this mean data is being taken from my PC or is Avast stopping this and just displaying for info.

Appreciate advice.

Usually not.
