AdSense does not own every ad on the internet. There are are hundreds of different companies that offer advertising, and thus, Google cannot control what happens with other ads.
Try uninstalling any apps or browser plugins you've installed that might come with ads. It's up to you ensure your browser and devices are clear of malware or virus. Run scans on your system.
If using a computer/laptop check your browser settings. Look for an adblocker.
If using a mobile device, uninstall apps that are free since most come with ads.
If you are experiencing popup ads and your phone is an Android device see:
Turn pop-ups on or off
- On your Android phone or tablet, open the Chrome app .
- To the right of the address bar, tap More Settings.
- Tap Site settings Pop-ups and redirects.
- Turn Pop-ups and redirects on or off.
