[entrée HijackThis] WPDShServiceObj.dll

Bonjour a tous

j'ai des ralentissements depuis peu alors que je viens de formater mon Xp. j'ai fait un tour dans HijackThis et il y a quelques entrées que je ne comprend pas, j'ai fait des analyses en ligne et ces entrées sont inconnues, je vous les mets en gras... j'ai deja nettoyé mon ordi avec Ccleaner + TuneUp Utilities 2006 RegistryCleaner, Regseeker etc...
