Does my television have a virus if so how do you get rid of it?

Hello, I have attached photos, my siblings recently connected a Nintendo Swich from Saturn to the Samsung TV. Since then, the bar that can be seen in the photo keeps showing up who knows what that could be and how to get there

Reset TV to factory settings

It's a horizontal navigation bar, not everything you don't understand is a virus. Could be that you got into the TV sales mode.

This is not a navigation bar that disappears every now and then appears at the top or bottom, but you can't click anything

The television will have switched to shop demo mode

or it comes through the Smart Hub

Best to reset to factory settings.

Thank you worked

I'm happy, greetings to you
