Particularly, wallstreetnews.com. This is an especially annoying tracking cookie, as it blocks any navigation to what I was originally doing at the time of its obnoxious arrival. I can`t do anything in that current window that I want to unless I minimize it. Then I have to open the "tools" section of the browser I`m using, go into the "privacy" settings and type in the name of the cookie I want to remove. This removes it, but unless I restart my computer I can`t get rid of the minimized window that started the mess. Oh, I forgot, I can use "Ctrl Alt Delete" to get into the running applications and stop that tracking cookie by deleting it. But, I still have to do the above all over again when I once again go online to some of the same sites or even my email, and this nasty little application of some kind (labeled "tracking cookie") reappears. I want to find a way to PREVENT it from getting into my computer. My virus program won`t do it (AVG 9.0), or I have yet to find a way to use it effectively.
