You may also want to think about looking for a thrid-party app if you are really serious about stopping these applications.  Blocking them and/or keeping up with new versions/apps/sites is getting more and more difficult.

Status: offline 		The best way to block an HTTP thing is to watch the traffic and make an HTTP filter that blocks based on a unique signature you see in the traffic.

For plain HTTP it is easy to use Wireshark or network monitor to do this.  For HTTPS you can use ClearTunnel to get inside the SSL and TrafficLog to dump it out.
