Is my computer safe with Windows Defender?

Episode 1653 (14:58)

Dave from Crystal River, FL
Windows Defender

Dave has a Windows 10 PC running Windows Defender as his antivirus. Is that a good idea? Leo says yes. Defender does everything you need it to do, as long as you keep it updated. But AVS software can also give you a false sense of security. The last line of defense is your online behavior. That means avoiding clicking on links or opening attachments.
