Eugene Kaspersky told news agency Reuters on Friday that his cyber security firm that bears his name would see a 'single digit' drop in U.S. sales this year as a result of suspicions about his company's ties to the Russian government, but global revenue should still increase. From a report: By turns frustrated and defiant in an 80-minute interview in his Moscow office, the founder and head of the embattled antivirus software maker denounced what he called an "information war" against his company, repeatedly asserting that "we've done nothing wrong." Anton Shingarev, Kaspersky Lab's vice president of public affairs, also told Reuters during the interview the company had abandoned efforts to sell its services to the U.S. government and that it would wind down its Washington-area subsidiary, KGSS. Kaspersky Lab has become a lightning rod in recent months as it has faced allegations by the U.S. government that its antivirus products can be used by Russian spies to conduct cyber espionage. Office Depot, Staples and Best Buy have stopped selling Kaspersky's security suite in their stores.
