Mapping the Malicious Sites on the Web
McAfee SiteAdvisor did an interesting study about the number of malicious sites per domain on the web: https://www.siteadvisor.com/studies/map_malweb_mar2007.html
They have an interactive map that helps you to get an overview of the different threats per domain.
Finally it made me think whether it was a wise decision to register halbheer.info........
