Hello Donald,
You may have that set as your homepage. If you are using Safari, you can update your homepage by following these steps:
Your homepage is the page that normally appears when you first open Safari.
- Open Safari if it is not already open.
- Choose Safari > Preferences, and then click General.
- Do one of the following:
- To use the page in the current Safari window or tab, click “Set to Current Page.”
- To use another page, type its address in the Homepage field.
- To use a blank page, delete the contents of the Homepage field so that the field is blank.
- If you also want the homepage to appear whenever you open a new Safari window, choose Homepage from the “New windows open with” pop-up menu.
