Annoying pop-up trying to make me update or upgrade

Since 1 or 2 days this thing is popping up, how can I turn it off?

The program wants that I “confirm” the desired level of protection, but it looks like the update notification and a don’t want to update (using Avast Free AV v12.3.2280)

I already had done this, so that’s not the solution.
AvastUI > Settings > General > Status Monitoring - uncheck the Program version

12.3.2280 ?
Latest 12.x version is 12.3.2279
If you are not using a business version, first to do is performing a clean installation with the latest version.

As has been explained really a lot of times, you can disable the pop-ups in the paid versions.

I know about the normal pop-ups that disappear after 20 seconds for example, but I don’t mean that.

It is a sort of “forced-update” pop-up, it tries to make me update or upgrade and doesn’t disappear, only when I click on the X.

I don’t want the latest version as I know it has a lot of bugs.

12.3.2280 is right

Version 17 is much more stable now and doesn’t have many bugs. It also has improved protection with the behavior shield. On top of that, it’s not vulnerable to DoubleAgent whereas version 12 is…

One moment or another, you need to update to the latest version.
Like it or not, but there will come a moment that a “pushed update” will take place.

You installed avast to help protect your system against malware.
Using a old(er) version increases the risk of a infection a lot.
Either you protect your system in the best way possible or don’t do it at all.

using a old(er) versions is like putting a lock on your front door while keeping your windows and back-door open.
