Now tell me where you are supposed to click to download the actual application. It confuses me, and I'm an experienced user who knows to look out for these sorts of things. I have no idea how normal people ever find the damn thing.
My question is: whose fault is this? Is it Paint.NET's, for allowing the ads onto their site? Or is it the ad network's (Google, in this case), for accepting the ads into their network?
Google should not allow ANY ads that contain a Download button, when the page has a link containing the text "Download." These ads can have no other purpose but to confuse users who are looking to download software. The problem is that Google makes money from these ads, and these ads have fantastic clickthrough rates. If they banned these types of ads, they'd make less money.
The author of Paint.NET is making good money every time a user mistakenly clicks on such an ad. This money also reduces his incentive to get rid of the confusing ad.
I get around this problem by running an ad-blocker, so I only see the one legitimate download link. But most users do not.
This is how industries get regulated -- when they refuse to regulate themselves. I hope Google realizes that and takes action on their own initiative...

I did find this, but I've never used it: http://code.google.com/p/openpdn/
The best rule of thumb is: if it looks shady, don't go there ever again. Another: every good program has an author, and this author has a valid, non-malware-installing link on his/her website.
For me blocking advertisements online is no longer about blacklisting bad sites, but whitelisting the few good ones I want to support.
They'll probably make a one by one pixel link that links to the clean download file.
You'd probably have to have a button to toggle this on and off.
The download link for the actual product will often really be a redirect to a page with a "your download will start in 5 seconds" and then some JS triggers the actual download.
Even the legit download will usually offer you toolbars and crap anyway.
I think that may make it useful enough...
