Thats a new one

From http://www.stopbadware.org/home/guidelines

A website is a badware website if it hosts or distributes badware and doesn't meet one of the exceptions described in Section II. This includes, but is not limited to, websites that do any of the following:

* Host or distribute badware directly on their site;
* Automatically redirect to a website that hosts or distributes badware;
* Link to executable files that are badware, whether hosted on their site or another site;
* Link to another website that automatically attempts to install badware by exploit onto the user's computer;
* Contain substantial links (either in nature or number) to other website(s) that predominantly host or distribute badware.

From what Ive seen every one of the sites that had that warning - and yes its been around a few months - has actually had a hacked script put on their pages (on the server) by someone else, or is intentionally doing it. In most of the cases it was a hacker that had gained access to a tgps server and installed the trojan script - then allowed it to copy itself to every page it could find.
I also noticed that Google is very quick about removing the notice as soon as its fixed so they must do some kind of re-botting for those sites it lists that way
