invader in autostart-group(winme)

xupiter toolbar loader had invaded my autostart-group in winme. spybot(a fantastic free german tool) could detect and destroy it only halfway. or maybe it just invaded once more. firewall-popup-warning came every few seconds telling me that xupiter tried to be executed. it seems i have blocked it, but i can still see xupiter-entry in autostart-group. how can i get rid of this?
