Hi
Unfortunatley the port un UltraSurf is 9666 on localhost, and the software is using this as a proxy it is injecting into the IE on the fly. This equates to a website called http://Ultra1

One way of controlling the program, I have found so far, is to place ultra1 in the Restricted Zone in Internet Options / Security / Restricted Sites of IE. Go to Custom Level and set all items to Disable or High Safety except Popup Blocker.

The program appears to make a lot of DNS calls to find the servers it is using. Blocking the servers it talks to may be another way, but it is not using port 80 or whatever your proxy server is.
