Kaspersky believes that he is the victim of geo-political events, the struggle between the two countries to Kaspersky as a tool.
In a statement of defence, the company noted that "Kaspersky Labs has nothing to do with any government, it has never helped, nor does it help any government in the world to engage in cyber espionage."
A US spokesman, through Reuters, said the decision was "reviewed and carefully considered" and its main priority was "to ensure the integrity and security of the U.S. government system and network".
