An anonymous reader shares a report: A Russian software-maker, whose products are banned for use in federal information systems by the U.S. government, is seeking to remain in the North American market and prove its products have no hidden capabilities. Kaspersky Lab Inc. will close its Washington D.C. office that was selling to the government and will keep working with non-federal customers in the U.S. via its remaining offices in the country, vice-president Anton Shingarev said in an interview in Moscow. The company also committed in October to open its product's source code to an independent third-party review and plans to open new offices in Chicago, Los Angeles and Toronto next year. "This allows independent experts to verify that our software has no hidden functionality, that it doesn't send your files to third parties, doesn't spy on you and fully complies with the end-user agreement," Shingarev said. The U.S. banned government use of Kaspersky software in September, citing founder Eugene Kaspersky's alleged ties to Russian intelligence and the possibility its products could function as "malicious actors" to compromise federal information systems. The move caused concern about the company's products in other markets, including the U.K.
