[HijackThis] DCOM et LSASS Exploit

Bonjour,

Je viens de remarquer que j'avais depuis ce matin des messages recurrents de la part d'Avast.
On m'annonce une tentative d'intrusion via DCOM et LSASS.

Je me suis apercu via Google que de nbreuses personnes avait ce prob.
Comme solutions on propose soit de ne rien faire, soit de passe un antivirus.

J'ai l'antivirus en ligne de Symantech. Il m'a rien trouvé.
Il ya qques jours, j'ai pendant qques secondes, baissé la protection de mon firewall à 'faible'..Me demande si j'ai pu attrapé qquechose durant ce laps de temps.

Je colle mon log hijack au cas ou :
