If you don't remember installing it, most likely it has been installed along with another software. As you can see on the review page of the product, BroadCam Video Streaming Server is used to stream videos and it installs a web server on your computer that can be accessed by any computer on your home network. If you don't need it, you can safely uninstall it using Add or Remove Programs feature:

If you have Windows Vista or above you need to go to Start > Control Panel > Programs > Programs and Features, select the BroadCam Video Streaming Server and click on Uninstall.
