The Justice Department recently said it has taken several steps to disable a network of computers infected with the Coreflood program that steals private and financial information.
According to the department, more than two million computers have been infected with Coreflood, which allows cyber criminals to gain online banking information and passwords.
The department also said it has received a temporary restraining order, allowing the government to send commands to infected computers to temporarily stop the Coreflood program through a hosted server.
"The actions announced today are part of a comprehensive effort by the department to disable an international botnet, while at the same time giving consumers the ability to take necessary steps to protect themselves from this harmful malware," U.S. assistant attorney general Lanny Breuer said in a statement.
The amount of cyber criminal activity increased significantly during the first quarter of 2011. According to an internet security company, 73,000 new threats were released on a daily basis, increasing 26 percent from the first quarter of 2010.
