The error log from the Netgear FWG114p (small 4 port firewall) reports these warning messages, like the one below - I understand the ones where it blocks access to some sites (I had put some keywords to reject those websites) - but what does this one

Administrator Interface Connecting[TCP] - Source:192.168.79.4,4974 - Destination:192.168.79.1,80 - [Receive]

indicate?  Does it mean that some agent is trying to connect to the firewall interface?  192.168.79.4 is one of the computers on the network, and 1 is the firewall.

That message is telling you that 192.168.7.4 is using a browser to connect to the administative web page of the router.  

Basically someone is accesing the setup screen of the router.   It could just have been you looking at the logs.  If you know for sure that .4 wasn't accessing it at that time legitimately, then it might be a virus or trojan.

Thanks Kevin  -  noone was accessing the admin interface or looking at logs - since I did not see any "wrong password" attempts does that mean that whatever malware agent wasnt successful ?
Why then would a malware connect without attempting to log in ? Just to see the login page ?

IF it is malware, it will try to exploit many things.  It might get your router model information to pass on to some controlling site, for someone to come back and hack against it.
