Bonjour cocochepeau,
Thanks for your response.
First I should explain that in the last hour, I downloaded Malwarebytes (free) from Softpedia (http://www.softpedia.com/dyn-postdownload.php/4da55095eb250a3742025ebdcf058222/580a4e8d/13ebe/0/1?tsf=0
...and something was found and removed from Firefox. It wasn't named 'Bing' but Bing has now been removed.
I had previously tried changing the default search as shown in your link. But the only search provider listed was Google.
For your inspection, I've pasted the clean log file from ADWCleaner at the end of this post.
But first I'll paste in the log of the successful scan run by Malwarebytes. It will tell you more. I'll separate the two log files with rows of asterisks. Firewall was disabled for the Malwarebytes scan of course---but not for ADWCleaner.
Thanks.
Rog'
