I now get the attached from the Avast Online Security extension in Microsoft Edge web browser. It appears the blocking of trackers now requires payment. I uninstalled it after years of use. 
Surely you can do that in your Edge browser (which I don’t use).
I used ASB add-on when it first came out, but I gave up on it because I didn’t like the clutter in search results. In all honesty I don’t need it and I feel savvy users don’t really need something like this. I don’t fear any of the heading in the screenshot.
I use Firefox 101.0 and there is much in the settings to prevent some of those headings. I also use add-ons (uBlock Origin, and uMatrix) to block ads/cookies, etc. that can be used to track you.
You don’t actually say what Avast Program version you are using ?
So I have no idea why you would be getting an Add for Avast One ?
Other than if you had Avast Free and they are trying to switch you to Avast One paid version. If you are happy with what you have, ignore it and X it out.
It’s an advertisement to install Avast One.

I think we know that, but the unknown factors are:
What Avast Program ‘skinnyJM’ is using.
If he is using Avast Free, then surely the AOS should cover the tracking aspect (and to some degree the browser and add-ons they use already) ?
Though that advert is for Avast One in skinnyJM’s post and not Avast One Free - Personally I feel a switch from Avast Free to Avast One Free is a downgrade (lose of configuration to be considered).
I myself use Avast Free, and I noticed the other day that the Avast Online Security browser extension stopped working properly. Please see my replies in the other thread that silentjim had started:

I ended up sending a Bug Report, as Asyn had suggested I do.
As I mentioned I don’t use the Avast Online Security browser extension, based on having Avast Antivirus with the Web Shield and Firefox with tight controls. I also have a slew of blockers as I mentioned in my first reply, so I don’t find ASB brings anything else to the party for me.
Hopefully your bug report will bring prompt action.
Dev-Info: [i]We made Anti-Tracking as premium feature in Avast One available countries. This feature is premium in Avast One and we were offering it for free with AOSP. However, there is a bug for users in Avast One available countries running AV Product (free or premium). In this case, Anti-Tracking should work without the limitation.
Fix was already posted to BETA and we expect it will be published to PROD sometime this week.[/i]
I use Avast One Essential (Free)
Based on post by Asyn it may just be a bug.
Thanks for all replies!
You’re welcome.
