Great, glad UltraSurf can be of use to some people
ONE THING to note though - if you experience connection problems with Internet Explorer after using UltraSurf, it's because UltraSurf has applied a proxy server settings to your connection and not undone it when you've exited UltraSurf. Usually, it does delete the proxy server settings but if it doesn't, here's what you do:
Go to Internet Properties, then Connections, then highlight your internet connection and click Settings. Where it says Proxy Settings, untick the box. That will sort it out.
But otherwise, there should be no problems with UltraSurf. It's not a program, it just automatically configures settings on your PC, and none of my spyware/virus/trojan detectors (Kaspersky, Spyware Guard, Spybot Search & Destroy) detect anything untoward.
