Yesterday Lifehacker offered up a guide to protecting your Windows PC from the Conficker worm; today they present another option: the free net service OpenDNS. And this is how OpenDNS works according to its own David Ulevitch:
The latest variant of Conficker is now churning through 50,000 domains per day in an attempt to thwart blocking attempts. Consider this: at any given time we have filters that hold well over 1,000,000 domains (when you combine our phishing and domain tagging filters). 50,000 domains a day isn’t going to rock the boat.
OpenDNS will continue to identify the domains, all 50,000, and block them from resolving for all OpenDNS users. This means even if the virus has penetrated machines on your network, its rendered useless because it cannot connect back to the botnet.
Setting up OpenDNS on your router is a breeze; just go to their website and follow the simple routine.
