a report by IID (Internet Identity) indicates that machines at 12% of Fortune 500 companies and 4% of government agencies are still infected with the malware (http://internetidentity.com/news/blog/686-iid-finds-12-of-fortune-500-still-infected-with-dnschanger#). When their systems are taken offline on the 9th it will lead to loss of productivity and may make it harder to service their customers.

Facebook and Google are sending notices to users that browse to their sites from a DNSChanger-infected computer. However, even if you haven't been notified of an infection you shouldn't breathe a sigh of relief and consider yourself in the free and clear.

When the FBI disables the temporary servers it will break infected system's access to the internet but it will not remove the malware from those systems. Take a few minutes to ensure that you're not kicked offline on July 9th.

First, open your internet browser and go to http://www.dns-ok.us. If your system is infected you'll see a red image with the words "DNS Resolution = RED." Alternatively, a green image with "DNS Resolution = GREEN" means that your computer is looking up IP addresses correctly.

Unfortunately, a green isn't necessarily an all clear either. Some internet service providers have created their own mini-DNSChanger servers which allow infected systems to bypass the FBI servers to access the internet. This means that while you won't lose access to the internet on the 9th you may still be infected.
