Occasionaly I get a window that pops up that tells me how I can buy their software to get rid of pop ups. That's extortion in my opinion, so I don't want to purchase their software nor would I trust them.

I get this even when I don't have IE running, so I suspect this program came with some other software I loaded.

What's good to find find and remove this kind of software? Is there a way to tell what I instaled to get this as well?

Thanks
Kenny
