When do you see the pop-ups, BS? If they're only on AB, then it's likely that they're part of the the site's own advertising, so there's nothing that you can do about them (other, possibly, to start searching Amazon for something like sexy lingerie, so that you see ads for such clothing instead of ads for McAfee!).
If you're seeing the pop-ups elsewhere though, it's likely that your PC has malware on it. (I'm assuming, of course, that you're actually using a PC, rather than a phone or tablet). Download and run AdwCleaner to zap it:

(There's no installation process; you simply run the downloaded file directly).
