Sometimes when I'm online just doing homework or browsing the web my Internet Explorer tab section will start continuously oppening tabs and the only way I can end this is shutting down my computer and restarting it. Does anyone know why this happens or how I can stop it from happening??

Check your keyboard buttons because sometimes happen while any key stuck on continuous pressed but with your case there is might be problem of virus/spyware so, scan your computer with some strong anti virus or spyware.
