Going back to my original post it would appear after some searching that the underlined blue text is something called intellitxt, and is created by vibrantmedia an advertising scam that hijacks just about every webpage. Further searching shows something called Greasemonkey will put a stop to it but it requires a little more computer knowledge than I have. Norton, Avast and AVG dont highlight it as a virus, and Malwarebytes ignores it. I thought at first it had worked but wrong again. No one else seen this?
