How to remove Archive for blog category

Hello Everyone,
I’m using Business Corp 2.0 theme by NewWpThemes.com and I wanted to get rid of “Archive for the “blog” category” heading from my webpages.
The website is: https://www.qagroup.ca
Can someone guide me how to remove this “Archive for the “blog” category” from my wordpress theme.
I checked in archive.php file but I have no idea what to remove.
Here’s the code:
<?php get_header(); ?>
<div class=”span-24″ id=”contentwrap”>
<div class=”span-17″>
<div id=”content”>

<?php if (have_posts()) : ?>

<?php $post = $posts[0]; // Hack. Set $post so that the_date() works. ?>
<?php /* If this is a category archive */ if (is_category()) { ?>
<h2 class=”pagetitle”>Archive for the ‘<?php single_cat_title(); ?>’ Category</h2>
<?php /* If this is a tag archive */ } elseif( is_tag() ) { ?>
<h2 class=”pagetitle”>Posts Tagged ‘<?php single_tag_title(); ?>’</h2>
<?php /* If this is a daily archive */ } elseif (is_day()) { ?>
<h2 class=”pagetitle”>Archive for <?php the_time(‘F jS, Y’); ?></h2>
<?php /* If this is a monthly archive */ } elseif (is_month()) { ?>
<h2 class=”pagetitle”>Archive for <?php the_time(‘F, Y’); ?></h2>
<?php /* If this is a yearly archive */ } elseif (is_year()) { ?>
<h2 class=”pagetitle”>Archive for <?php the_time(‘Y’); ?></h2>
<?php /* If this is an author archive */ } elseif (is_author()) { ?>
<h2 class=”pagetitle”>Author Archive</h2>
<?php /* If this is a paged archive */ } elseif (isset($_GET[‘paged’]) && !empty($_GET[‘paged’])) { ?>
<h2 class=”pagetitle”>Blog Archives</h2>
<?php } ?>

<?php while (have_posts()) : the_post(); ?>
<div <?php post_class() ?>>
<h2 class=”title” id=”post-<?php the_ID(); ?>”>” rel=”bookmark” title=”Permanent Link to <?php the_title_attribute(); ?>”><?php the_title(); ?></h2>
<div class=”postdate”><img src=”<?php bloginfo(‘template_url’); ?>/images/date.png” /> <?php the_time(‘F jS, Y’) ?> <img src=”<?php bloginfo(‘template_url’); ?>/images/user.png” /> <?php the_author() ?> <?php if (current_user_can(‘edit_post’, $post->ID)) { ?> <img src=”<?php bloginfo(‘template_url’); ?>/images/edit.png” /> <?php edit_post_link(‘Edit’, ”, ”); } ?></div>

<div class=”entry”>
<?php if ( function_exists(“has_post_thumbnail”) && has_post_thumbnail() ) { the_post_thumbnail(array(200,160), array(“class” => “alignleft post_thumbnail”)); } ?>
<?php the_excerpt() ?>
</div>

<div class=”postmeta”><img src=”<?php bloginfo(‘template_url’); ?>/images/folder.png” /> Posted in <?php the_category(‘, ‘) ?> <?php if(get_the_tags()) { ?> <img src=”<?php bloginfo(‘template_url’); ?>/images/tag.png” /> <?php the_tags(‘Tags: ‘, ‘, ‘); } ?> <img src=”<?php bloginfo(‘template_url’); ?>/images/comments.png” /> <?php comments_popup_link(‘No Comments »’, ‘1 Comment »’, ‘% Comments »’); ?></div>

</div>

<?php endwhile; ?>

<div class=”navigation”>
<?php if(function_exists(‘wp_pagenavi’)) { wp_pagenavi(); } else { ?>
<div class=”alignleft”><?php next_posts_link(‘« Older Entries’) ?></div>
<div class=”alignright”><?php previous_posts_link(‘Newer Entries »’) ?></div>
<?php } ?>
</div>
<?php else :

if ( is_category() ) { // If this is a category archive
printf(“<h2 class=’pagetitle’>Sorry, but there aren’t any posts in the %s category yet.</h2>”, single_cat_title(”,false));
} else if ( is_date() ) { // If this is a date archive
echo(“<h2 class=’pagetitle’>Sorry, but there aren’t any posts with this date.</h2>”);
} else if ( is_author() ) { // If this is a category archive
$userdata = get_userdatabylogin(get_query_var(‘author_name’));
printf(“<h2 class=’pagetitle’>Sorry, but there aren’t any posts by %s yet.</h2>”, $userdata->display_name);
} else {
echo(“<h2 class=’pagetitle’>No posts found.</h2>”);
}

endif;
?>

</div>
</div>

<?php get_sidebars(); ?>
</div>
<?php get_footer(); ?>

Thanks….
