The FBI said that there are still more than 330,000 computers believed to be infected with the DNSChanger malware, with just weeks to go before a court order to cut off their ability to communicate with the rest of the Internet. Fully 77,000 are located in the U.S., according to data provided to Threatpost. The data was culled from servers operated by the Internet Systems Corporation (ISC), in conjunction with the FBI, following an international crack down on the online scam in November, 2011.
