The idea of the pop-up creators advertising how to stop them hasn't filled me with confidence. I would imagine its a bit like fax and e-mail spam, where responding just confirms to them that their message is getting to someone. I only started getting pop-up messages a couple of weeks ago, and although I removed downloads I thought might be culpable they still persist. In fact, there's one from Britney just now! I'm with you PhilLew - ideas for stopping them!!
