I'll go with the small red download button in the middle.
It could be the very bottom one, but it probably says advertisement under that and it's just been cropped out.
But even the correct button is likely to launch you into a popup to try and get you to download a "downloader" of some description, as if that's not literally the sole function of a fucking web browser, and then suddenly you've been taken to livejasmin.com or a sketchy gambling site targetted at Asians.
