I just went there and saw a fake start download button, but it was with the 'AdChoices' network, not AdSense.
EDIT: I guess AdSense is involved with AdChoices somehow. My mistake.

The AdChoices icon is used by many ad networks, not just Google's, to indicate that there's per-user targeting happening. [1] But if you click on that "AdChoices" button and you get an AdSense help page.
The link from the ad is to https://googleads.g.doubleclick.net
I don't see how it can't be a Google-sold ad.
I suspect the reason that kind of ad is allowed (despite being deceptive IMHO) is that it's not just a download link. It also indicates that it's an ad for a driver update site (which makes it even shadier to my eye, but probably not violating any policies).
