is a plugin that comes bundled with some games, and consists of a WildTangent Web Driver, WildTangent Multiplayer Library, WildTangent Updater and WildTangent GameChannel.
You can remove it, but you might find that your game won't work properly if you do.
This is what Wildtangent have to say about their software:
"We collect certain system configuration information through our software such as your computer's CPU speed, video card configuration, and DirectX version. We use this information to adjust the way our games and other software work in order to ensure their best possible performance. We also collect certain product usage information through our software such as the number of product launches and time spent playing a product.
Our software includes a service that updates the GameChannel menu located in your Start folder with the latest games. Periodically, your computer will connect to our servers to receive the latest product updates. New product availability information or messages are transparently and unobtrusively transferred to your computer in the background, allowing you to review them later when you're off-line. You can access these product updates in the Game Channel folder of your start menu."
Draw your own conclusions from that.
