Best Buy has stopped selling software made by the Russian company Kaspersky Labs.

NEW YORK — Concern rippled through the consumer market for antivirus software after the U.S. government banned federal agencies from using Kaspersky Labs software on Wednesday. Best Buy said it will no longer sell software made by the Russian company, although one security researcher said most consumers don’t need to be alarmed.

Best Buy declined to give details about why it dropped Kaspersky products, saying that it doesn’t comment on contracts with specific vendors. The Minneapolis Star Tribune first reported that Best Buy would stop selling Kaspersky software.

The U.S. Department of Homeland Security cited concerns about possible ties between unnamed Kaspersky officials and the Kremlin and Russian intelligence services. The department noted Russian law might compel Kaspersky to assist the government in espionage.

Kaspersky has denied any unethical ties. It said Wednesday that its products have been sold at Best Buy for a decade.

Nicholas Weaver, a computer security researcher at the University of California, Berkeley, called the U.S. government decision “prudent,” after arguing for such a step in July. He added by email, “for most everybody else, the software is fine.”

The biggest risk to U.S. government computers is if Moscow-based Kaspersky is subject to “government-mandated malicious update,” Weaver wrote this summer.

Kaspersky products accounted for about 5.5 percent of anti-malware software products worldwide, according to research firm Statista.

Another expert suggested consumers uninstall Kaspersky software to avoid any potential risks. Michael Sulmeyer, director of a cybersecurity program at Harvard, noted that antivirus software has deep access to one’s computer and network. “Voluntarily introducing this kind of Russian software in a geopolitical landscape where the U.S.-Russia relationship is not good at all, I think would be assuming too much risk,” he said. “There are plenty of alternatives out there.”
