If you are looking for a free, fast and reliable proxy solution for anonymous surfing, Here is a new multi-platform application, PaperBus (ad-supported) which lets you surf anonymously and bypass internet filters.
Paper bus (brought you by Open Terrace Ltd the same company that made commercial proxy service Freedur) is very easy to use. Simply install, and run. No registration required.
The only down side is there will be an ad web browser tab popping up in every twenty minutes while you are using it.
Another interesting feature of PaperBus is that you can create a list of websites you don't want to surf through PaperBus.
