Viburnum are not invasive plants. They are actually quite desirable as they have good fall color, fruit for birds, and spring flowers. They usually require little in the way of pruning except to shape the plant a bit. Because they bloom in spring, they should be pruned shortly after blooming so as not to prune off next year's flower buds. 

If the shrub stems are very thick and lack much in the way of foliage and flowers, you may want to try renewal pruning.
