Try Blender. It's free, not spyware/adware, never have to pay for it. Updated all the time by authors world wide. Open source software at its greatest. It has a manual that you can download for it, but last time I knew (last year) it wasn't updated for the newest version, so you have to either skip steps or find other ways to do them. For a free program, it's really pretty good. It's better than paying $7,000 for Maya.
