This site automatically opens and closes when I open my messenger window, what is it? Ad-ware doesn't find anything.

Someone reported having popups from the esampler.tns-global.com
before at another forum.  This thread here.

He had one similiar to you

That's really strange.  I don't understand it though.

Are you using IE by the way ?

Then I searched "Taylor Nelson Sofres' because that's the title of the page.   In general, it was a site that surveys uhm, internet traffic  ?  I'm not sure.

I'm not using IE i use firefox, but it still opens, jsut when I open the messenger window. It wouldn't take addresses or your own addresses would it? There appears to be no adware related to it either.
