    if ( ! is_admin() && ! is_search() && ! is_archive() ) {

        // Add the category ID to an array of excluded categories. Add multiples like this - ( '5', 'ID' )
        $excluded = array( '-1' );

        // Note that this is a cleaner way to write: $wp_query->set('category__not_in', $excluded);
        set_query_var( 'category__not_in', $excluded );

    } // end if

}
