Time Warner and AT&T among others have yet to upgrade their DNS servers. Now that there is some rouge code on the loose that is designed to target these DNS servers it is a VERY DANGEROUS time to be surfing the Internet using the default DNS services from one of these companies.

This is not a complicated change  but if you are on a network that has yet to upgrade their DNS servers, (Check Here) you are at EXTREME RISK!
