Ordinateur Infesté Help !!!

Bon voila, j'ai un ordinateur vachement lent, souris qui ralenti, clavier qui des fois ne répond plus et pourtant c'est un Pentium 4 3ghz. Il y a forcèment quelque chose qui cloche ! J'ai donc fais un scan online avec panda software qui m'indique que j'ai un Trojan et des dizaines de Tracing.cookies. Je fais des scan répétitif avec A-Squared, Spybot"Search and Destroy" et avec Kaspersky 6.0 et ils ne trouvent rien, rien du tout !
Voici le compte-rendu de panda software de Total Scan en faite :
