The U.S. government announced on Thursday that it is banning the sale of Kaspersky antivirus in the country, and is asking Americans who use the software to switch to a different provider.

The Commerce Department’s Bureau of Industry and Security said it imposed the “first of its kind” ban, arguing that Kaspersky threatens U.S. national security and users’ privacy because the company is based in Russia.

“Russia has shown it has the capacity, and even more than that, the intent to exploit Russian companies like Kaspersky to collect and weaponize the personal information of Americans. And that’s why we are compelled to take the action that we’re taking today,” U.S. Commerce Secretary Gina Raimondo said in a call with reporters.

News of the ban was first reported by Reuters ahead of the announcement.

Kaspersky will be banned from selling its software to American consumers and businesses starting on July 20, but the company will be able to provide software and security updates to existing customers until September 29. After that, Kaspersky will no longer be permitted to push software updates to U.S. customers, according to Raimondo. 

“That means your software and services will degrade. That’s why I strongly recommend that you immediately find an alternative to Kaspersky,” Raimondo said.

Raimondo said that U.S. consumers who already use Kaspersky’s antivirus are not violating the law.
