Changing footer

I have a theme called attitude which I downloaded online, and whenever I try to remove the translators credit (not the original theme maker credit), it locks my site and replaces it with a photo saying something along the lines of “this site has been locked due to copyright violations! contact : XXXXXX” which really pisses me off since it should be a free work and I’m free to do any change I want… no one should implent such codes in my site.

Question is… how do I remove it?
I looked up the footer and this is what’s written inside of it:

<?php

/**

 * Displays the footer section of the theme.

 *

 * @package 		Theme Horse

 * @subpackage 	Attitude

 * @since 			Attitude 1.0

 */

?>

	   </div><!-- #main -->

	   <?php do_action('attitude_after_main'); ?>

	   <?php do_action('attitude_before_footer'); ?>	

	   <footer id="colophon" class="clearfix">

			<?php do_action('attitude_footer'); ?>

		</footer>

		<?php do_action( 'attitude_after_footer' ); ?>	

	</div><!-- .wrapper -->

	<div class="tcenter mb2"><a href="https://www.sagive.co.il" style="font-size: 12px; color: #888;" rel="nofollow"><?php _e('Hebrew By Sagive SEO', 'attitude'); ?></a></div>

	<?php do_action( 'attitude_after' ); ?> 

<?php wp_footer(); ?>

</body>
