OK, I am used to and have no issue with google ads here or anywhere popping up related to the content of what I am looking at right now. For example, if I go to a the Thai food forum here and there are ads about Thai food, no issues. However, recently I am noticing google ads related to topics from my OTHER browsing, sometimes browsing I have done hours ago. It's downright creepy! For example, perhaps I have been researching Mexico on other pages. So I see ads here at TV about Mexico that have no relation to the content I am viewing here. I do use gmail and I realize they know everything. Is this expected ad behavior here? Do I have some demonic ad-bot infecting my machine?

It's so called interest based advertising, here is some info from the help pages:
