Last night, my computer just kept bringing up pop up ads advertizing a free ipod mini. They come up even when the browser is closed. A dozen at a time, until the toolbar is filled with them. They're internet explorer pop ups, so I unistalled ie (I'm using Netscape now) but they still come and I can't get rid of them. Is there any way to stop this without having to reinstall windows and delete all my files? I've got a pop up blocker, but that still doesn't work. Thanks.
