The department states if there are ties between Kaspersky or any of its workers to the Russian government, it could compromise U.S. National Security.
Kaspersky has more than 400 million customers worldwide, but it has never succeeded in becoming a major supplier to the USA government.
In response to those admissions, the company issued a statement flatly denying the accusation of "inappropriate ties with any government".
Also on Sept 14, the US Senate came a step closer to passing legislation that would codify the Trump administration's ban, voting to expand an amendment to a pending defence policy spending bill to prohibit both federal civilian and military agencies from using Kaspersky Lab products.
Russia's Zapad Military Drills Seek to Send a Message to the World
Western analysts say the figure of 100,000 personnel taking part in Zapad comes from aggregating all these drills. Belarus has formally notified the OSCE that Zapad will be held on Belarusian territory from September 14-20.
"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 US national security", the department said.

Republicans on the House Science Committee wrote to Eugene Kaspersky on Thursday asking him to testify at a subcommittee hearing on September 27.
Pentagon confirms American ISIS fighter captured in Syria
The US military confirmed on Thursday that an American fighting in Syria for the Islamic State has been taken into custody. The American fighter, whose identity was not released, is not the first American ISIS fighter captured on the battlefield.
But two months ago, the news website Bloomberg reported it had seen emails between chief executive Eugene Kaspersky and senior Kaspersky staff, outlining a secret cyber-security project apparently requested by the Russian intelligence service FSB. The latest is electronics retailer Best Buy which said there were "too many unanswered questions" about the firm's software.
It also cites a Russian law that allows intelligence agencies to seek information from Kaspersky.
Federal contracting databases reviewed by Reuters show only a few hundred thousand dollars in purchases from Kaspersky, and an employee told Reuters in July the company's federal government revenue was "miniscule". "This wasn't an easy action for the United States government to take, and it will also have significant ramifications for corporations that use Kaspersky", explained Hamerstone, who is the Practice Lead for the Governance, Risk, and Compliance division at security consultant TrustedSec.
