stop highlighted text/links to pop up ads

That has nothing to do with Jetpack. It sounds like it might be a computer virus. Make sure you have checked your computer for viruses.

True. Here’s a response from someone else who reviewed this:

I visited the website and do not see text links with pop up ads. I checked the site with IE, Chrome and FireFox. The pop ads must be coming from your Browser and not the website itself. You must have some sort of toolbar or add-on or extension installed in your Browser. Your Browser software is installed on your computer.
