Hello 'loob...',
Do you have some sort of ad blocker on your computer? People who use the browser
Firefox like that Ad-block Plus, and for Internet Explorer users they have Pop-up Blocker.
Do you have either of these? I'm not sure what else you mean by "AdChoice", - or if it
is something you signed on to initially?
Pop-up ads, however, are infuriating, ebay is rife with them, so you will need an ad blocker
of some sort if you haven't got one already.
You can download them free from the internet, - just use a search engine to find one to
suit your system.
And of course, - it never hurts to clear your computer's cache and cookies (temporary
internet files) and restart your computer.
