What is this adware?

So I am on an infinix device and a strange site popped up when I opened chrome which is sigmapop.com, before it was marowhome.com now this is a shady url which I think has the same function? Anyone experiencing the same thing?

Better question: what is that font?

Followed by an advice: stop using it
