How can I effectively block ultrasurf which is being used on our company network. With ultrasurf all web filters applied on the network are useless. Does anyone have a solution to this problem?
You can easily go ahead and block the file it self so it is no allowed to be run by anyone or everyone based on the rules. You do this through group policy. Here is a short tutorial: http://www.maketecheasier.com/block-specific-programs-in-windows-7/
