What went wrong?
Hello,

I just see today, In settings, I chose this "Ask where to save each file before downloading". But Chrome starting to download before I selecting the download location. When The green bar on the Chrome icon is full (Windows10), I click on the save button and then the huge file is being saved. That's it, it is already downloaded on the location selection screen. So, If it is an exe that is automatically downloaded by an infected site, It has already been downloaded. Sorry for my english. 

Have a nice day,
Joseph
