To uninstall crapware on your computer, you sometimes need to modify the registry. That can be a bit tricky, but it usually does the trick. Just delete the files then. You may need to reboot during the process because Windows won't allow you to delete files in use.
Just scan through the registry for different strings like "coolweb" or "gator". Should do the trick.
I don't mind when they tell me and offer me options, but when a program doesn't tell you - that's a problem. All the more reason to read the license agreement. Personally, I think Guitar and Drum Trainer has one of the best license agreements around
