JACKSONVILLE, Fla. – Tens or even hundreds of thousands of computer users could be unable to get online this summer.
The FBI is warning all computer owners to check for a type of malware, called "DNS Changer," similar to a virus.

PCs infected with DNS Changer were used by a group of hackers for fraud.
