The picture below is a example of a FB Scam known as Like Jacking:

DNSChanger had infected 4 million Computers/Routers but 350,000 Computers/Routers are still infected with the DNSChanger. The FBI has arrested the criminals responsible for the DNSChanger. The DNSChanger infects the Computers/Routers and so anything you do goes through to the DNSChanger servers which will give you malware/popups. The FBI will shut down the DNSChanger servers on July 9th which if you are still infected will kick you off the internet. All Computers on that same Router are infected with the DNSChanger so you have to disconnect from the internet and disinfect each Computer from it. Please check to make sure you are not infected with the DNSChanger at: http://www.dns-ok.us To fix and protect against the DNSChanger visit: http://www.dcwg.org To watch a old video I made explaining about DNSChanger and how to disinfect it: http://www.youtube.com/watch?v=8XVp6hciJFY For more info visit: http://www.zdnet.com/blog/networking/dnschanger-to-knock-350000-users-off-internet-this-july/2332
