"The risk that the Russian government, whether acting on its own or in collaboration with Kaspersky, could capitalize on access provided by Kaspersky products to compromise federal information and information systems directly implicates USA national security".
The appearance before Congress would be Kaspersky's most high-profile attempt to address long-standing accusations that his firm may be conducting espionage on behalf of the Kremlin.
Software firm Kaspersky Lab is back under the microscope of the federal government - this time, leading to an FBI investigation for possible links to Russian security services.
A U.S. government decision to stop using security software from Kaspersky Lab is "regrettable", the Kremlin said on Thursday.
The statement from DoHS orders all federal departments and agencies to "identify any presence of Kaspersky products on their information systems in the next 30 days, develop detailed plans to remove and discontinue present and future use of the products in the next 60 days".
Kasperksy Lab has rejected allegations from the US Department of Homeland Security (DHS) that it has ties to the Russian Government and poses a threat to national security, and expressed disappointment with the decision to ban the use of its software on US Government systems.
The laws in question are applicable only to telecommunications companies and ISPs, and Kaspersky Lab has never and will never help any government with "cyberespionage or offensive cyber efforts", the company said. "We don't have any secrets, we don't do anything bad against our customers and against governments".
The American store chain Best Buy has stopped selling Kaspersky products, but Mr Kaspersky said he had had positive discussions with other retailers. "While I don't have insight into the dealings of the Russian government and Kaspersky, we've seen in the news over the last few years that USA companies regularly cooperate with USA intelligence agencies ... why would we think that this isn't happening in other countries too?"
DHS has given Kaspersky 90 days to provide proof that its products are not facilitating espionage for Russian Federation or to offer mitigating measures.
The Department of Homeland Security gave federal offices 90 days to eliminate any software manufactured by Kaspersky Lab from their information systems.
Republicans on the House Science Committee wrote to Eugene Kaspersky on Thursday asking him to testify at a subcommittee hearing on September 27. There may also be other agencies in which the software is being used without the knowledge of that agency's chief information security officer.
But he denied that his company is involved in any Russian spying. In the Russian embassy in the United States, the ban on using Kaspersky Anti-Virus was called a continuation of russophobia.
The government ban should alarm any company that has been relying on Kaspersky's software to protect its business, said Nate Fick, CEO of computer security specialist Endgame.
