The captioned site occasionally hijacks my browser (chrome). If you want to observe what it does just type in the URL and you will get an immediate demonstration. It posts a "microsoft" warning that "Your Microsoft computer has been blocked..." and gives a number to call to resolve the problem (888-382-7416). Once launched the browser is locked. I am unable to switch to other open tabs or shut down the offending tab and must kill it in task manager to get rid of it.
Neither SuperantiSpyaware or Malware bytes find anything if I scan after I have an incident.
I have tried seaching for the URL both on web and your site, but do not find anything. Interested to know if you have any info on it.
