A computer "virus" destroyed information stored in personal computers at NASA and other government agencies, The New York Times reported Tuesday.

The rogue computer program, designed to sabotage a private company in Dallas, destroyed computer files over a five-month period beginning in January, the newspaper said.Damage to government data was limited, but files were destroyed, projects were delayed and hundreds of hours were spent tracking the electronic culprit, the Times said.

It was not known whether the program was deliberately introduced or brought in accidentally, but National Aeronautics and Space Administration officials have asked the FBI to investigate, the paper said.

Also affected were the Environmental Protection Agency, the National Oceanic and Atmospheric Administration, and the U.S. Sentencing Commission, the Times said.

The program "infected" close to 100 computers at NASA facilities in Washington, Maryland and Florida, NASA officials said.
