Demande d'aide analyse HijackThis

Bonsoir à tous,
je souffre d'un énorme problème: depuis quelques jours, mon débit est très très très fortement ralenti et ca me pose énormément de problèmes, j'ai lancé plusieurs scans (spybot, ad aware, rogue remover, malwareantibytes) mais ils n'ont rien trouvés...
Suite au message d'une personne sympathique, j'ai lu le tutoriel HijackThis et j'ai fabriqué un rapport, pourriez vous m'aider à le décrypter svp ?
le voila:
