Stormdemon : I got your mail containig configtool.exe. I checked it for viruses and trojans, nothing found. I ran it extensively with and the firewall never triggered. The tool is identical bit for bit to the original one. And finally, in the DLL dependency list, there's nothing about networking.

So I can really affirm : this configtool.exe would never access the network by itself.

The problem is related to something else... Maybe a trojan infected some Windows DLL called by configtool ? This would explain why the program name triggering the firewall is configtool.exe... Can't you find back which web site or IP was targetted ?
