Besoin d'un coup de main pas assez de connais

Bonsoir à tous,
Suite au conseil d'un amis j'ai téléchargé Hijack This, fait l'annalyse, mais besoin de conseils pour éliminer ce qui doit l'être. Mon ordi (Wind 98 SE)est très lent, et c'est probablement dû aux programmes non demandés .
Merci de m'aider à déterminer ceux à éliminer de manière correcte
Bonne soirée à tous
Claude
