Hello. I am sorry for replying in English, but I wouldn't feel good sending you something automatically translated.
We are already looking into this problem. It was reported here:https://forum.avast.com/index.php?topic=241932.0
We will inform you as soon, as we get more information about the problem. Can I ask you what version of antivirus are you using? You can check that by right-clicking on Avast icon on toolbar and clicking "About Avast" or "À propos d'Avast" if you have the program set in French.
