'verhindern' and 'unterbinden' both mean that something does not happen or does not continue. 'verhindern' is the normal, general word and fits many everyday situations. 'unterbinden' sounds more formal and is often used when something disruptive, forbidden, or unwanted is actively stopped. It fits, for example, with rules, authorities, school, or work. If you are simply saying that a problem should not arise, 'verhindern' is more natural. If someone deliberately stops disruptive behavior, 'unterbinden' is more precise.
