Federal authorities announced Tuesday that they have erased Chinese malware from thousands of computers across the United States.

The U.S. Department of Justice (DoJ) on Tuesday disclosed that a court-authorized operation allowed the Federal Bureau of Investigation (FBI) to delete PlugX malware from over 4,250 infected computers as part of a "multi-month law enforcement operation."

More than 4,000 U.S. computers and networks have had malware files deleted by the FBI, which said it did not collect other information during the remote operations.
