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