Avast no longer free?

I am use to needing to re-subscribe to free avast every year. I’m honestly not sure what time of the year I do that, but today I received an alert that my trial had ended.

When I look at the avast icon on my icon tray is says “Avast Internet Security. You are not protected!” I cannot seem to find any way to subscribe to the free service again. every option I click leads me to buying.

Did something change?
