Merci.

J'ai également fait une restauration du système en mode sans échec, plusieurs fois, car a plusieurs dates il ne veut pas changer, mais rien n'a fait.!!!
Merci.

J'ai fais comme dit avec Hijackthis et Ccleaner, apparemment cela refonctionne mes pg a l'ouverture s'ouvre comme avant.
Mais une question encore comment savoir ce que l'on doit fixé avec Hijackthis, pour moi c du charabia ..........
Encore merci.
