How to Ensure Internet Shutdown Tomorrow Won’t Effect You


internetTens of thousands of Americans whose computers are infected with malware will lose Internet service Monday. Here’s a quick explanation of what led to this impending Internet blackout and how you can avoid being left in the dark.

Over a year ago, hackers used an online ad scam to infect more than 570,000 computers around the world with malware called DNS Changer that could make the devices carry out tasks without their owners’ knowledge. The FBI wanted to shut down the servers that the hackers were using to control the infected computers, but they realized that the victims of the hack would suddenly lose Internet service if they did so.

The feds set up a transitional system that allowed them to take down the hackers’ servers while still allowing computers affected with the malware to get online.

But they’re set to pull the plug on that system at 12:01 a.m. Monday, July 9 – after that, anyone with an affected machine will be kicked off the Internet until they rid their computer of the malware.

So how can you avoid being among those who lose Internet?

First, it’s important to note that if your computer is infected with DNS Changer, your antivirus software won’t help. And if you use a Mac, don’t think you’re immune – Comcast reports that they’ve already spotted the malware on several Apple computers.

  1. To comment number 1:The fact that you are asking this question idicates that you are not following the article properly. Just log onto said site and take it from there.

  2. I had no trouble with my service until today July 11 and now neither of my two computers can connect to the internet—-I tried a different physical wifi site and still can’t get on—I also cannot get on a wired connection. Is there anyone who can comment?
