Thanks for all the instructions but I guess I'm not explaining myself correctly.
When I first posted my question, it was because I noticed that many of my favorite templates had been modified and included the following under the title:
"http://www.auctiva.com/stores/viewstore.aspx"
The page is already far too cluttered with all the ads eBay crams onto the page. So I wasn't asking how to remove the entire template, I was only asking if there was a way to remove that particular PART of the template.
My solution was to just chose other templates which do not contain this modification.

Thanks again for your quick attention to my latest response. It's much appreciated.
Thanks!
