function remove_uncategorized_category( $terms, $taxonomy, $query_vars, $term_query ) {

if ( is_admin() )

return $terms;

if ( $taxonomy[0] == 'product_cat' ) {

foreach ( $terms as $k => $term ) {

if ( $term->term_id == get_option( 'default_product_cat' ) ) {

unset( $terms[$k] );

}

return $terms;

}

add_filter( 'get_terms', 'remove_uncategorized_category', 10, 4 );
