"antivirus scan failure" with Chrome



I'm facing an issue, I can't download any files with Google Chrome. Whatever and wherever the files I wan't to dowload on Chrome, everytime I want to download something, it's cancelled and I get the following message : "antivirus scan failure".

However, when I download the exact same file with Forefox, I have absolutely no problem to do it. So there's only with Chrome that happens. I updated the latest versions of Chrome and Bitdefender but nothing changes.

Do someone face the same problem ? Has eventually a solution ?

Thanks in advance
