Help with remove posts in category on first page

Okay so I don’t under my theme at all or code but can someone make it that if the category of the post is “Products” (without quotes) it won’t show it. I tried my best but it doesn’t work. Here is “The Loop” (without quotes) page code.

<div id="post-<?php the_ID(); ?>" <?php post_class('clear'); ?>>
		<?php
				$thumb = get_thumbnail($post->ID, get_theme_mod('thumb_key'),get_theme_mod('thumb_key'));
				$width = get_theme_mod('thumb_width');
				$height = get_theme_mod('thumb_height');
				$auto = get_theme_mod('thumb_auto');

				if($thumb) {
					if($auto == 'Yes')
						$url = get_bloginfo('template_url').'/timthumb.php?src='.$thumb.'&h='.$height.'&w='.$width.'&a=t&zc=1';
					else
						$url = $thumb;

				} else {
					$url = get_bloginfo('template_url').'/images/default-thumb.gif';
				}

				echo '<a class="entry-thumb" href="'.get_permalink().'" title="'.the_title_attribute( 'echo=0' ).'"><img width="'.$width.'" height="'.$height.'" src="'.$url.'" alt="'.get_the_title().'" /></a>';
			?>

	<h2 class="entry-title"><a href="<?php the_permalink(); ?>" title="<?php printf( esc_attr__( 'Permalink to %s', 'themejunkie' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php the_title(); ?></a></h2>

	<div class="entry-meta">
		<span class="date"><?php the_time(get_option('date_format')); ?></span>
		<span class="meta-sep">|</span>
		<span class="meta-comments"><?php comments_popup_link( __( '0 Comment', 'themejunkie' ), __( '1 Comment', 'themejunkie' ), __( '% Comments', 'themejunkie' ) ); ?></span>
	</div> <!--end .entry-meta-->

	<div class="entry-excerpt">
		<?php the_excerpt(''); ?>
	</div> <!--end .entry-excerpt-->

</div> <!--end #post-->
