Ugly JPG

Sorry if I am posting this out of place, it IS my first post.
1. I had to use the add on wiz to reinstall and of course I got the very ugly jpg with the logo.
2. It still appears for a second or so even after I created two new profiles which do NOT have a path to this ugly jpg file.
3. Where can I find this file, I need to remove it permanently from the system. —Thanks!
