Barre indésirable

Bonjour,
J'ai une toolbar qui se positionne en bas de mon écran à chaque fois que j'ouvre inetrnet explorer. son site est http://lop.com/passthrough/newpass2.html.
Quelqu'un peut-il m'aider à la faire disparaître. Je mets ci dessus ce que me met HijackThis. Je ne connais pas grand chose à l'info.
Merci.
Aliban
