what is hxhihkekt.bid?

This alert appears on my Android phone - neither Malwarebytes nor Sophos Mobile Security detect any malware on my phone. It appears that it may be a popup on the website you can see behind the alert. Some html alert pages with Android logo and hazard stripes may also occur saying the same. I don't click on anything, just close the page or app displaying the alert.

I have search for any reference to this and nothing comes up in google.

can anyone advise what action I can take to fix/block this?
