this article over at oriellynet shows you how to stop them pop-ups that are comming from spammers. you may have gotten these before. its a message from someone outside your network (if you have one) sending stupid things like “pay us to stop these” or something like that. anyway, this article shows you how to do it without paying them. my firewall blocks these, so i dont know what they look like, but the article is interesting. looks like windows xp only.
