Enlever open search web

salut !

je viens vous demander de l'aide svpparceque j'ai cette barre open search web sur mon pc et je n'arrive pas à l'enlever. j'ai essayé avec adware, spybot mais ça n'a rien changé.
hier j'ai réussi à l'enlever avec hyjack mais malheureusement aujorud'hui elle est revenue !!
j'ai supprimé msn plus car j'ai lu que ct peut etre ça qui m'avait installé ce truc.
je vous laisse le copier coller ..
