Sure, this is fine, but Google seems to plan to block sites which show malicious ads served by Google's AdSense. That's idiotic.
This is the second case in a month of Google punishing web publishers for using Google products. (The previous case was Google punishing non-https search results, when in fact many of Google's own web publishing tools don't support https.)
And I'm willing to bet Google will make a special exception for itself. I actually posted a screenshot on my G+ page yesterday of the most recent fake download button I saw online... On a YouTube banner ad, served by Google AdSense.
Do they have a history of making exceptions for themselves? If not, then you winning this bet will be quite a big deal - it'll show them as anti-competitive. They'd be forcing customers to use their AdSense product instead of just-as-good competitors.
Maybe they'll just give this "malvertising" detection software to AdSense who can then filter their own content before it hits websites. I'd be more willing to bet this will be the beginning of Adsense cleaning itself up than what you suggest.
Yes. On last week's story, a commenter mentioned how they decreed that web pages which showed a full-page ad on landing would be penalized in search, yet they themselves continued to show a full-page ad in mobile GMail for the GMail app, and it remained the first hit for "e-mail".
