Avast and IE 11

How can I get avast to work on IE 11? I don’t have Java and I won’t install it. When I click on Avast account the little orange circle just keeps spinning.

I wanted to sign up for a new account for my husband but I don’t know how to do that. I use Firefox for my account.

See screenshots.

Looks like there is currently a problem with the portal as I am also unable to access it
