If your PC is one of the possible 500,000 computers worldwide that has聽been hit by the DNSChanger virus,聽chances are, you already know it. Because of a move by the FBI today, all infected computers have gone offline. Many reports suggest that the damage today has been minimal. But if your computer still carries the virus, fixing the problem just got a lot harder.聽

The good news: If you're reading this article, this machine is clearly not affected.聽

DNSChanger聽is an computer virus that allowed criminals based in Estonia to redirect your Web browsing. Instead of visiting the website that you wanted,聽the virus rerouted you through a rogue server that would feed you advertisements. And, if anything happened to these rogue servers, the virus would keep trying to reach them unsuccessfully, effectively knocking your computers offline.聽

Well, last year, the FBI and Estonian authorities busted the black-hat hacking ring聽who set up the virus. For the聽past eight months, the Bureau has arranged for a series of servers to stay聽online and carry the traffic that would otherwise be downed by cutting off the hackers鈥� servers. Now, however, those FBI servers have been shut聽down. You鈥檙e on your own.

If one of your PCs is hit by DNSChanger, you'll need to figure out a way to get anti-virus software onto that computer.聽

First, here are several clean-up programs listed by the DNS Changer Working Group.聽These programs should remove the virus and related programs, but you'll need to get them onto the infected machine through a USB drive, CD/DVD, or some other way that does not involve the Internet.聽You can do that on your own, or have a computer聽professional do it for you.

Once your computer is set with a legitimate DNS, you will want to聽check your router, if you have one, to make sure it is also using the聽proper address.

As the DNSChanger Working Group cautions, 鈥淐hanging DNS is only one of聽the functions of the malware kits. The malware could have been used聽for capturing keystrokes or acting as a proxy for traffic to sensitive聽sites like bank accounts or social media.鈥�

You will want to check all of your financial accounts, and other聽sensitive information sources, to make sure they have not been聽affected. You will also want to change your passwords.

If you still find that you are not clear of the problems hatched by聽DNSCharger, experts encourage you to call your Internet service聽provider for help.
