Hello, I'm fairly new to MAC. I've been a PC user for years and now have an iMAC w/Leopard. I visit the Internet Movie Database on occasion ... jeepers my one vice ... and only there do I get a popup that is actually hidden under everything. I never touch it, I reset Safari, or Quit Safari. I looked this place up and see it is some sort of tracking cookie/malware? on PCs. There are "Spybot"/software solutions answers, but no MAC solutions. I would like to block the site, but I can't figure how to do it as I could in IE. I'm the only user on this computer. Thanks for your help. Dollly
