This isn't the only intimidation tactic employed by the Trojan. It also disables access to Task Manager and other Windows tools to limit the user's ability to close the disturbing page which is actually hosted on the victim's PC found at the following location:

I suspect that this trend of giving fake Government alerts to propagate malicious content is only going to trend upwards. Some download locations for this threat can be seen here:
