In some instances you may be able to remove the paneling and paint the walls directly. But often paneling was installed with both nails and adhesive, and you could damage your walls if you try to remove the paneling. Also, in some cases the paneling was placed directly on the wall studs with nothing behind it. When you're ready to start painting, make sure that your paneling is made of solid wood. Some paneling actually consists of a vinyl print that simulates the look of wood. To check, sand a small area on the wall. Vinyl coatings come off quickly, revealing the pressboard underneath. If your walls have a vinyl or thin veneer finish, you'll need to take extra care when painting them.
