I'm glad you posted this. I would be concerned too. Thanks, graceand ham for the help.
Look at the top of your Cute page and see the triangle sign and "Not secure"? That's what your protection service is reading. It's been there for a few years now. If you're concerned about your login having been compromised, change it by pretending you forgot your login and then taking the link that comes in an email to change your login to something totally new. And write it down somewhere convenient!
