Je n'arrive pas à supprimer http://istart.webssearches.com

Bonjour,

J'ai un problème, quand j'ouvre Mozilla Firefox, au lieu d'avoir Google comme d'habitude, j'ai http://istart.webssearches.com à la place. J'ai étais dans outils, option, général et j'ai rentrer Google mais lors du démarrage d'internet, je ne tombe plus sur Google, par contre, quand je clic sur la petite maison, j'ai bien Google ...
De plus, dans mes programmes, je ne vois rien qui n'est pas normal ...
J'ai fait un CCleaner et un Malwearbites (qui a trouvé pas mal de choses ...) mais j'ai toujours ce problème !
J'ai vu sur ce forum que je ne suis pas la seule à avoir ce problème et j'ai fait un JRT comme l'avait conseillé quelqu'un.
Je vous envoie le rapport que celui-ci m'a écrit :

J'espère que quelqu'un pourra me dire ce que je dois faire car je n'y connait pas grand chose ...
Merci d'avance
