A little background:

In 2007 a group of Estonian and Russian hackers allegedly exploited the internet advertising pay per click model, by impostering as an internet advertiser.  In order to increase their clicks and site traffic, they allegedly created a piece of malware, called DNS Changer, which tampered with the DNS Setting on your computer or your router. 

The DNS is a setting that acts like the “yellow pages” for the internet, when you type in a web site address, the DNS turns it into a numerical IP address which then directs it to the actual website.

By tampering with the DNS, these hackers were able to beat the system, and cause computers to re-direct all web sites that you tried to access, to instead go to their pay per click advertising site, which then increased their pay per click revenue.  This practice is called "click hijacking."

Fast forward to 2011, when the FBI got around to fix the problem, the challenge was they could not shut down the rogue servers because any infected computers ( estimated at 4 million) would then not be able to access the interent because the fraudulent DNS would re-direct them to non existent sites, thus they would have no interent.

So the FBI set up temporary servers at the fraudulent DNS address, to re-direct properly, in order to give malware-infected Internet users time to fix their computers.

Fast forward to now, the FBI temporary servers will shut down Monday, July 9.

So, if your interent stops working Monday and you are wondering what happened, you probably were infected.

If you were really infected this whole time, in all reality, Monday would not be such a doomsday for you, because you probably would have been having a whole lot of other computer problems, and possibly do not have adequate virus protection which would have caught this.  Thus you may have been limping along and this is now the final straw for your computer.

Also, over the past year many of the ISPs, like Verizon and Comcast have been monitoring your internet traffic and having been sending letters to their subscribers whom they detected had been infected and had been accessing the fraudulent DNS servers.

If you have adequate and up to date virus protection, and have not had any history of viruses or strange computer behavior like redirection or pop ups, then you should not have to worry about this.

Of course, if you have a problem, my best recommendation is to just shut off your computer, so the problem does not continue to manifest and spread throughout your computer, and call your local computer tech to assist you.
