We’ve posted about this a couple of times before, but since the deadline to update your machines is quickly approaching, the message bears repeating.

DNSChanger is a malware that has changed many machines to use a handful of malicious DNS servers. The hackers that set up these malicious DNS servers and propagated the malware hoped to cash in by controlling the adverts that were displayed on infected machines. The FBI uncovered the network and took steps to disable the rogue servers, and also set up temporary “clean” servers to provide DNS services for the infected machines. However, these temporary FBI servers are being taken off line effective July 8.

So what does this mean to you? Well, if your machine was infected with DNSChanger and the infection has not yet been discovered and corrected, as of July 8 your computer will simply not be able to connect to the internet. Providence has run a check of our clients’ machines and found none that have any issues, but if you haven’t done so already you may want to check your home machines and other computers that you use.

The FBI has made available an excellent document that fully explains the issue and provides guidelines on how to deal with it. But if you have any other questions or concerns about DNSChanger and any of the machines that you use, don’t hesitate to give us a call.
