Yes if I uninstall KAV then I can connect with no problems, I get an almost immediate online response from sunrise.net-7.org. With KAV installed I can ping / nslookup / full traceroute to sunrise and nothing seems wrong. Something, somewhere in KAV is interfering with the process...I did notice the UDP connections pop up when the launcher is trying to authenticate, the one thing I haven't done yet is watch resource monitor with KAV uninstalled to see what the differences may be.
KAV doesn't include a rule based firewall just the port monitoring but it's clearly the problem. I just find it odd that suspending KAV's services doesn't resolve the problem, only removing it completely works. KAV installs a NDIS 6 network filter that handles a lot of it's protection mechanisms but even uninstalling that doesn't work. I'll try to isolate what tcp/udp connections are being blocked.
