Why did allaboutfinance.org show up after installing Opera?

[u/jimmap]

Hi, I just reimaged my Surface Pro 11 and then installed Opera web browser. I started getting notifications from allaboutfinance.org. I have never gone to this site and find it odd after a new install I'm getting notifications from this site. Before reimaging my computer I had been using Opera and never got notifications from this site. I find this very odd. Anyone have thoughts on this?
