Weird scripts running on my sites…

I have five sites that are all hosted under the same account that all of the sudden are loading slow or not loading at all. I’ve noticed at the bottom where it shows what’s loading, random url’s like click.htcstore.org, clickga.net, etc. By no means am I a WordPress guru so I can use help figuring this out. I’ve spent hours trying to find help to no avail. A couple of the sites are courageouschurchdfw.com and caryscreations.com.
