Ouverture explo ou IE devenu hyper lent

Bonjour,

suite au passage XP SP2 sur mon PC, l'ouverture de IE ou Explorer est devenu thyper lent (1 minte après avoir cliqué)
Les autres applis s'ouvrent normalement.
Ad-aware ne voit rien, avast non plus, voici ce que me donne "HijackThis"

Que faire ? J'ai vraiment les boules !!!
