DNS Changer and Internet Access On July 9, 2012

By now, many of you have no doubt heard of the DNS Changer malware that affects mainly Windows and Mac computers. The piece of malicious code changes how your computer receives DNS (Domain Name Service) information when you are surfing the web. Without accurate DNS information, your computer cannot connect to the Domain Name Server(s) that resolve the human-readable domain names you type into your browser to their corresponding machine readable IP address numbers. The following blog nicely explains how all this works, how to use the "dig" utility in UNIX/LINUX systems to retrieve numerical IP addresses, and where to go to determine if your computer is infected. Go to : Kudos to the person(s) who put this article together - it's the best I've seen written on this subject!
