A report has been released by StopBadware.org that shows half of the websites that are pushing malware are hosted by just 10 networks. Six of these networks are internet service providers (ISPs) which are based in China and these networks hosted more than 41 percent of the malicious websites according to the article at The Register.

A separate report was released  and the results were similar. In that report, the results show that the three biggest offenders are Xinnet Bei Gong Da Software, Beijingnn, and Todaynic.
