Hello, osecurity-optimu.
The ads in QuickBooks are guides that serve as a helpful reminder. I know this seems not necessary if you keep seeing these pop-up ads over and over. But if they're affecting your navigation experience, I recommend clicking on the X or No, thanks buttons. This will temporarily prevent the pop-ups from showing up again.
However, If you‘re referring to marketing advertisements pop-out and other forms of ads on browser, you can check out this article for a more detailed instruction: Block certain ads.
Should you have other questions about navigating around QuickBooks, feel free to leave a post below. I’m here to help. Stay safe!
