Any plugin to disable comments?

I am getting tired of deleting spammy comments even after having disabled the comments. Not sure why people n bots are still able to leave comments.
Is there another solution to this nuisance? Like a plugin perhaps?

 

find this code in your single.php or page.php
<?php comments_template;?>
then comment it out like this
<?//php comments_template;?>
or just entirely delete the whole thing.
