I seem to have the same site keep opening in a new tab on the internet. I use Firefox and have have good luck, better than IE10, buts that me. I am inserting an image of the screen to which I have been unable to locate the culprit to this.
I have a link to MBAM in my sig, de-select the 30 day trial when you install it.
What is the site you get the popup, or popunder, from?
There are a lot dodgy sites that always want you to update this or that (crap) or install some player or another. Fake virus scan which will warn you that you have an infection, also crap.
