You'll never be able to completely stop all ads from popping up—some will always get through. Most ad blockers focus on removing the harmful or annoying ones, but a few ads are actually allowed through as "approved" or "acceptable" ads, depending on the blocker you're using. In some cases, advertisers find clever ways to bypass these blockers altogether. If you're still seeing too many ads, it might be worth trying a different ad blocker that has stronger filtering options. Also, check the settings of your current blocker—some are set to allow certain ads by default, and tightening those settings could make a big difference. It may take some trial and error, but stronger protection is definitely possible.
