I was trying to download FileZilla as well when I first encountered the 'installer'. I stopped the download a couple of times, then searched around and found a direct download link in a thread in FileZilla forum. Second time I was in a hurry, I just downloaded the installer anyway, then carefully opted out of installing those crapwares. However I encountered the new installer when trying to download FileZilla only. I had to download a couple of different software since then, but those did download directly, no installer.
