The FBI is on the case

In November of last year, the FBI launched an investigation under the codename Operation Ghost Click that targeted the malware DNSChanger. The malware is suspected of infecting over half a million computers in the United States. 

The FBI plans on turning off the servers of the criminals who plagued people with computer infections. Originally, the servers were planned to be turned off on March 6, but the FBI extended the deadline to July 9th, 2012 to avoid causing some people losing internet service. 

I would be sure to have malware protection turned on and have your wifi network password protected. The FBI does do a lot of surveillance perhaps using msvehicles mobile command centers to monitor cyber criminals.
