OK. There are a lot of hoaxes out there, but this is not one of them.
Better safe than sorry.

DNS—Domain Name System—is an Internet service that converts
user-friendly domain names, such as
www.fbi.gov <http://www.fbi.gov>,
into numerical addresses that allow computers to talk to each other.
Without DNS and the DNS servers operated by Internet service
providers, computer users would not be able to browse web sites, send
e-mail, or connect to any Internet services.
Criminals have infected millions of computers around the world with
malware called DNSChanger which allows them to control DNS servers. As
a result, the cyber thieves have forced unsuspecting users to
fraudulent websites, interfered with their web browsing, and made
their computers vulnerable to other kinds of malicious software.

Checking to see if your computer system is infected is easy. You can
visit this webpage recommended by the FBI and click on the "Detect"
button to check your system. My system wasn't infected. But then I use
some good Antivirus and Anti-malware software.
