I have been using Kaspersky antivirus for years. The first one was Kaspersky Internet Security. When its license expired, I bought Total Security. For the next four years, they automatically renewed my license for free. Two days ago, they notified me by email to switch to Kaspersky Premium. In the email, they sent a link where I could download the application. I downloaded the application and installed it. It was automatically activated. When I asked them for the license key, they told me that there was no need for a key, because the application is automatically activated because it is tied to my account. I thanked them very much. So, I only paid for Kaspersky once, and that was 5 years ago. Every subsequent year, the license is automatically renewed...for free.
