Hi David, let me translate my post for you.
For a few days a banner saying that my Free Antivirus Avast licence was going to expire was being displayed at the bottom of the main screen. I tried to reactivate it for a year, but it did not work.
Today, it did expire. Banner now says ‘"Your Avast Free Antivirus license is no longer valid’.
I uninstalled Avast with AvastClear in safe mode. I deleted all remaining files, I cleaned the Windows registry and I deleted cookies just in case. Then, I reinstalled Avast from scratch.
I was surprised to see the same banner!!!
I clicked on REACTIVATE and I selected the free version.
Avast Premium is proposed, I selected “No, thanks”.
Result: I am back to the main screen, with the same unchanged banner ‘"Your Avast Free Antivirus license is no longer valid’.
