Just Curious Please Check it out

Hi Anyone, I was just curious about my findings, after getting the url address of this site (see attachment) on my website, I use wordpress, as I checked further it turns out there are about 2,560,000 websites that have this problem too. I suspect the plugin WP-Slimstat is the cause, because the 5 websites I use these Slimstat stats plugin, so for those of you, who use this plugin check if your site also has a link address that I mentioned in my attachment.
