Virus - Moto G (2nd Gen) - s.iktmmny.com redirect link on words on page

I have a Moto G 2nd Gen. Lately, on many of the sites I visit (including .gov), many of the words have become links. When clicked on, they redirect to the domain s.iktmmny.com/(etc....). It's rather inconsistent, but certainly annoying! I have installed a number of antivirus apps, but none are able to detect anything.

Any advice or comments are appreciated, I can't find a single shred of evidence that anyone else has had the same problem.
