Last November the FBI arrested six Estonian hackers in a raid called “Operation Ghost Click” and dismantled their cybercriminal enterprise.
In a nutshell: the hackers created some malware dubbed DNSChanger that had the ability to redirect infected computers to hacker servers controlled by the fraud ring, which then piped web ads to users, ultimately putting millions of dollars in the cybercriminals’ pockets. The FBI disabled the ads on the rogue servers and will officially shut them down on July 9, 2012.
Lets recap! If your computer is infected with DNSChanger, you will not be able to access the Internet on Monday because the FBI will be shutting down the two remaining rogue servers. You can test your computer to see if it is infected at the FBI site or at www.dns-ok.us. Everyone else (aside from DNSChanger-infected computers) will still be able to browse the Internet on Monday.

”As many as 64,000 Americans’ computers may still be affected by malware that will cause them to lose Internet service come Monday, so if you haven’t already, make sure you aren’t among them.” –Salvador Rodriguez | Los Angeles Times
