Basic Ad Blocker no loner working

Thank you for providing us the info, John.
Please check the sensitivity of Adblock & change it according to you prefrence (either Essential or Balanced).
Tip : Setting it to strick might cause pages to not load properly. 
If it is already configured properly, then you may need to try resetting the browser once to check if it helps (Open browser - Menu - Settings - Advanced - Scroll to the bottom of the screen again and click Restore settings to their original defaults, then select Reset settings to confirm).

Hi John,

We apologize for the inconvenience caused to you.
We will check and help you with this issue.
May I know since when you are facing this issue please?
Have you tried to uninstall and reinstall AVG Secure Browser and then check if it helps?
If possible, please share us the screenshot of Adblock not working in order to check and help you further.

The basic ad blocker is no longer working. Any reasons for this please?

Around 1 week.

No - would not consider such a radical step.

There's no need for a screen shot. Pages I regularly access are now completely full of Ads and the Privacy Guard is showing no pages total blocked

Hi John,

We're glad to look into this & help you. 
From your description, we're uncertain whether the Adblock feature is unavailable or not working. Would you be so kind to clarify it for us?
Also, let us know the version of AVG Secure browser. (Open browser - Menu (3dots at top right corner) - Help & About AVG Secure browser - About AVG Secure browser).
