I am using IE9 on a Vista machine.\n\nThere is something going on that was first a bother and is now a worry. I\nwent to a business-card printing site to check their pricing and within a\ncouple of hours every website I open has business card printing\nadvertisments on it. I went to a security camera site to check their\npricing and within a couple of hours every page I open has security camera\nadvertisments on it. It was a bother, now it's a worry.\n\nWhat the hell is going on? Is there a way I can stop it? I was thinking\nabout checking the prices of a particular model of car and I have resisted\nfor a couple of days just, at least, until someone tells me what or if there\nis anything I can do about this.\n\nThanks in advance for all help.
