Safari ad showing in lower left corner

[ae6dx]

Recently in Safari I am seeing an ad showing in the lower left corner. I'm wondering about possible malware but don't know how to fix it. Also I use AOL Mail and am unable to get it to load in Safari. All other sites load ust fine. I have checked all my extensions as well as tried reseting Safari with no luck.

Hmmm did you remember ever installing any third party tools or search bars?
