[WINDOWS XP] un ordi qui a besoin de soins!

Salut à tous!

Je viens de récupérer un ordi dont jai besoin pour mes études et il ne fonctionne pas bien, je pense qu'il a au moins un virus et des chevaux de troie!

Comme je suis une quiche dans ce domaine j'ai suivi la procédure que tout le monde adopte c'est à dire un scan à l'aide d'hijack this
Si vous avez des conseils judicieux je suis preneuse, l'ordi rame comme c'est pas permis et des fenêtres de pubs s'ouvrent sans arrêt sous IE

voici le résultat:
