Skype calls to feature ads big enough to interrupt any conversation. This is what happens when MS gets their hands on anything decent and ruin it for users. http://arstechnica.com/information-...ads-big-enough-to-interrupt-any-conversation/
I wonder if the AdMuncher developers will get a blocking script done for that carp in Skype. They have scripts that block adverts in other apps, not just the browsers...
Just map their ad server to 127.0.0.1 with the hosts file. Or even better, block it with your firewall.
