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

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.

The US has again taken court-approved action to remove malware from privately-held internet-connected computers across the country, part of an effort by a number of countries to combat infections of a version of the PlugX malware from a Chinese-based group that has infected thousands of Windows machines around the world.
