DNS Changer is not new, and, in fact, the miscreants behind it were busted last November. The issue now is that millions of computers that had been infected are still pointing to the DNS servers that were controlled by these people behind DNS Changer. A court ordered law enforcement to maintain legitimate DNS servers at the addresses previously used by the DNS Changer servers so that affected users would have time to clean up the infection on their systems and reset the DNS addresses in their routers and PCs, so they would not lose internet access. The allotted time to do that runs out July 9, when the interim DNS servers will be shut down and users will need to be getting their DNS service from mainstream providers.
Norton detects DNS Changer as Zlob or TIdserv. If Norton hasn't alerted to the presence of either of these threats on your computer, then you do not have to worry about the coming deadline - your DNS service will not be interrupted.
