No. Kaspersky has been banned or heavily restricted in the US since 2022 after the US Department of Commerce cited national security concerns due to the company's Russian ownership and potential government access to user data. The NSA and FBI both recommend alternatives. If you're in the US, Malwarebytes is a safer, government-approved choice.
