Gros problèmes d'utilisation du PC

Bonjour tout le monde,
Je vais vous présenter le post de ma petite amie qui depuis hier se voit dans l'impossibilité de surfer sur le web - quand elle lance internet explorer une page google s'ouvre (frauduleuse je pense car les caractères y sont plus gros qu'auparavant et cette page dirige vers de mauvais lien et des fenêtres intempestives s'ouvrent). De plus son ordinateur semble réfléchir en permanence. Enfin, l'ordinateur se bloque la plupart du temps lors du démarrage ou de son arrêt et lorsqu'il parvient à démarrer les logiciels qui se lancent normalement au démarrage ne se lancent pas.

Ayant quelques notions mais cependant insuffisantes je fais appel à votre sciences pour m'aider à résoudre ce problème.

De plus voici quelques éléments que le logiciel Toolbarcop a trouvé sur son ordinateur : WVUNKAQN.DLL, QAHWFO.DLL, JKKHXPQK.DLL, ALCMTR.EXE mais encore SYSFUPW Qu'en pensez vous?

Voici le post
