Plugin added copyright notice to $cronimage

[D.Baker]

Hey guys,
I installed a bad plugin that shows a copyright notice when $cronimage is called. I've uninstalled the plugin and it is still there. I've looked around in the phrases, database and templates and can't figure out how to remove it.

I found this code in it's install XML if that helps:

';
		$vbulletin->templatecache['footer'] = str_replace($str_ga,$str_ga.addslashes($vbulletin->options['advert_ga']),$vbulletin->templatecache['footer']);
	}
	
	$advert_copyright = '<div class=\"smallfont\" style=\"text-align:center;\">PluginName By <a href=\"http://www.domainname.com\">&nbsp; XYZ</a></div>';
	$str_copy = '$cronimage
	<!-- Do not remove $cronimage or your scheduled tasks will cease to function -->';
	$vbulletin->templatecache['footer'] = str_replace($str_copy,$str_copy.$advert_copyright,$vbulletin->templatecache['footer']);

Any ideas on how I could remove this?

Thanks.
