Annoying messages from Avast Free - how to end?

Hi there, I noticed that Avast Free keeps me annoying me with online messages (buy now, update).
How to end this ?

Some more detailed information and or a screenshot of the pop-up would help.

Thanks David for the reply.

Removal of current software (Avast Pro maybe, trial version) plus installation of Avast Free edition may solve the “problem”.

In case I notice strange behaviour of computer I will start a new thread.

Enjoy your weekend!

You’re welcome.

If it is related to the same pop-up just come back to this one, the topic remains open.

Thank you, have a good weekend too.
