The global anti-virus software firm of Russian computer entrepreneur Yevgeny Kaspersky asked on Friday that Russian media "stop speculation" about his son, who has reportedly gone missing in Moscow.
"Kaspersky Lab calls on the media to stop spreading rumors and speculation about the events related to the family members of Yevgeny Kaspersky," the firm said in a statement. "Yevgeny Kaspersky is working normally, but he commented that the information being circulated is harmful for the company."
Ivan Kaspersky, 20, was reportedly kidnapped while on his way to work on Tuesday.
Russian news site Life News says kidnappers are demanding 3 million euros ($4.3 million) in return for freeing Ivan.
Kaspersky Lab - one of Russia's few stand-out successes not related to its energy sector - has neither confirmed nor denied the report.
