Will Your Internet Work on Monday? How to Check for DNS Malware

A nasty piece of malware called DNSChanger will kick thousands of Mac and PC users off the Internet on Monday, and there’s a chance you could be one of them.

The FBI is shutting down domains that have been affected by the DNSChanger malware, which has been circulating the web since as far back as 2007. The malware redirected Internet traffic to sites with paid advertisements where cybercriminals reaped profit from unsuspecting visitors.

The trojan’s creators — six Estonian nationals — shut down their services when they were caught and arrested about eight months ago.

Although the FBI has been urging consumers for months to check if their systems have been affected by DNSChanger, about 275,000 computers are still at risk of not having Internet access on Monday, July 9.
