So I installed Google Toolbar and for the longest time it blocked every unwanted pop-up. But lately pop-ups have been getting by it, and most are from Adznoodle or whatever. I have run spybot and other seach programs and there's no spyware on my comp. Are these new, sophisticated pop-ups? They seem to be ones that target specific site, like when I go to Delta.com Hotwire ads pop up. Any ideas?
