Completely delete comments from wordpress website

I have created new website in wordpress http://phoenixwebsolutions.net/ , you can see there is list of posts on home page. and you can see text on right corner "No comments" . same with other pages http://phoenixwebsolutions.net/about/, see msg. "Comments are closed." now i dont want this things to displayed on my website. i have tried everything, i have deleted wp-comments-post.php file, but i am not completely successful to vanish this texts. does anyone know how to remove this texts?

 

remove

<?php comments_template(); ?>
<?php comments_popup_link(__('Comments (0)'), __('Comments (1)'), __('Comments (%)')); ?>

Code (markup):

from index.php/page.php/single.php(theme file) file

 

i have checked my index.php file from current theme, but its blank file with 0KB size

You must navigate to the theme files to make these changes, not the files in the blog root.
