Analyse d'un hijackhis.

Salut,

Rien d'abracadabrant dans ton rapport HijackThis, hormis le fait que Windows ne soit pas à jour.

Donc, envisage sérieusement à faire ceci dans l'ordre :

1/ Scanne ton PC avec cet antivirus en ligne :
https://www.bitdefender.com/toolbox/
Clique sur "I Agree" et scanne tout le PC.
Pense à accepter l'ActiveX bloqué par la barre anti-popup du SP2 (elle clignotera en haut).
Copie/colle le rapport sur le forum.

2/ Fais toutes les mises à jour via Windows update :
http://www.windowsupdate.com/windowsupdate/v6/default.aspx

3/ Reposte un nouveau log HijackThis stp.

++

Salut deyshauna, si tu refuses GENERIC HOST PROCES, pas de navigation sur Internet, donc coche le, pour ne plus avoir à répeter la manip à chaque fois, je confirme les propos de Kristopher, rien de spécial dans ton log. bonne soirée.

bonsoir chers messieurs.
voici le nouveau rapport de bitdefender et de hijackhis. en passant je ne posséde pas de SP2 de windows.
merci.
