A dozen years ago there was the widely dreaded Y2K virus that threatened to wreak havoc on computers around the globe. Now there is a malware virus called DNSChanger that will spring into action when users log onto the Internet Monday expecting to access the World Wide Web through their own Internet service provider, or ISP.
"The risk depends on what malware is intended to do," said Arthur Anderson of Rye IT consulting service . Depending on the way it is coded, Anderson explained, malware can disrupt Internet service or even access data stored on your computer. That may include information about your identity, passwords and other information.
The DNSChanger malware threatens lock out tens of thousands of people from Internet access Monday, and it may also search out private information.
According to the FBI, the trojan virus will divert users from legitimate ISP servers to malicious sites that will alter their domain name server—the unique address of your computing device. Without access to the correct DNS, you would not be able to access Web sites, send e-mail, or use any other Internet services.
A Huffington Post report citing FBI data estimates as many as 277,000 computers infected worldwide and about 64,000 in the United States.
