Core.insightexpressai Pop-Up

This core.insightexpressai pop-up has been appearing every few days on my 2012 macbook air for a few weeks now. Just curious if anyone knows anything about it or how to remove it. I've been avoiding any banking or other personal info sites since the pop-up began just to be safe but would really like to remove whatever is hidden on my computer that is causing this. I've attached a screen shot of the pop up.

No, I cleared cookies, cache, offline website data, and everything else that be cleared under the preferences tab and this didn't seem to help.

I'm not sure how to clear that - and I've never seen it.
I'd be trying Onyx to clear things.
I'd be looking for browser add-ins that block ads and javascript.
On the web it says this pop-up is from a cookie tracking company - which I gather means it is involved in personalizing ads. Not something I want either.
