Hackers have been able to hijack hundreds of thousands of websites in the past 48 hours and insert redirects in them that take you to a sham security site. The attack has been dubbed Lizamoon after the first site to be infected. When you go to a site with this problem, you're taken to another site that says it's the Windows Stability Center. Windows does not have a Stability Center, it's a front for malware they install. Jerks. The attackers are taking advantage of a security flaw in Microsoft SQL Servers.
