Spam on Safari - Text enhance

Hi there,

A couple of days ago I got this stupid TextEnhance that keeps underlining some words at the websites I browse and when hovered onto shows all kinds of ads.
Tried to disable it thinking it was a Safari extensions but besides Cuevana Stream and Codec M I don´t have any other.
Could be a cookie, but can´t find it under the name of text enhancer or anything similar.

Has anyone encountered the same and managed to get rid of this awful spamming tool?

Thanks!
