Google Censors Badware

In conjunction with StopBadware.org, Google now sometimes censors results. See the PC World news report for more details. Basically, Google gives a warning page when a searcher clicks on certain results. The warning page has a link to the StopBadware site along with a "Or you can continue to . . . " with a link to the potential malware site. I can get it to work for the asta-killer site with a search like asta-killer. On mousing over the title, Google shows the link URL of http://www.google.com/interstitial?url=http://asta-killer.com/ in the status bar. However, the sub-site links under the URL do not have the interstitial warning link. Nor does Google give the warning on a search that might take me to a particular section of the site such as winzip registration code.
