The FBI has been contacting companies to tell them not to use Kaspersky AntiVirus Software because it represents a security threat, especially to power companies and other key industries vital to national security. Leo says it would have been better to just get the word out through the media and shows like the Tech Guy so that everyone could benefit from the warning. But truth be told, Leo isn't a fan of any antiVirus because it gives you a false sense of security. If you must use one, just use the one that comes with Windows. It's called Windows Defender and it does a good enough job. but the last best line of defense is your own online behavior.
