You should no longer be seeing pop-up ads on any of your pages. If you do, you may have at one time accidentally added the code that creates the pop-up ad to your pages. This could have happened if you used the "Save as..." command to save a web page to your computer and then reuploaded the page.
To remove the pop-up ad, you'll need to delete the pop-up ad code from your page. From your File Manager, open the page in the HTML Editor and remove the code between these tags:
<!--<SERVICE NAME="toto">--> and <!-- -->
You may also see a pop-up ad if you're using a browser older than version 4.0. If you're using a browser older than version 4.0 and would like to remove the pop-up ad, you may want to upgrade your browser to a version 4.0 or higher.
