DNS Changer Catch 22
July 9, 2012
By Roger Thompson

In my last blog I talked about the DNS Changer and its impact on victims.  Today, the DNS Changer deadline has arrived, which means victims of DNS Changer are kicked off the Internet until they have their computer fixed. 

An obvious problem is this: Many people need software to fix their computers.

So you have a catch 22…
Those that need to fix their computer need software, but the software is on Internet sites they can’t get access.

Well, the good news is this my friends.  I do NOT suggest simply installing software to fix the problem.  The truth of the matter is, if you were vulnerable enough to get nailed by DNS Changer, you were likely to have been hit multiple times by other malware. 

So I recommend the following steps to anyone who has been impacted…
(1)    First thing is DON'T PANIC. Although it is much talked about, only a very small percentage of people will have been affected, and if you can reach your favorite web site today, you are not one of them.

(2)    If you are one of the unlucky ones, it's not the end of the world. It's easy to fix. All you need to do is to (a) back up your data (b) format the disk, and (c) reinstall Windows. If that sounds too tricky, take it down to your local computer store, and they'll be glad to do it for you.

(3)    If you belong to the lucky majority, who have not been affected, it'd be a good idea to use this time to prepare for a future attack. Find a way to backup your computer automatically and regularly, and install an ICSA certified antivirus scanner.

Easy way out (but not as effective)…
If you are a victim, but do not want to reinstall Windows, you can use another computer to download the software from the DNS Changer Working Group page, and transfer that software to your impacted PC.

It is a tricky Internet folks.  Be safe.
