Google Malware Notice Only On Organic Result?

Colin McDermott posted on Twitter that Google shows a malware warning on the organic free search result for a site but not on the paid search ad.

Here is a screen shot that I was able to replicate:

Funny how on the same exact search results page, the malware warning only shows for the organic result and not the paid search ad. Which one is more delayed? The paid result or the organic result?

You'd think Google would run both through the same security checks?

The site was hacked a few days ago, but seems to be okay now.

But I guess not.
