Alerte élevée AVG : infection trojan ? [Résolu]

Bonsoir aloes,
Merci pour ta réponse.
Je pensais qu'avast était un des meilleurs antivirus gratuits... Dois-je comprendre qu'il ne tient plus trop la route maintenant ?? Tu confirmes ?
J'avoue avoir du mal à suivre : je suis passée en quelques années de norton à Kaspersky puis avast. Comment peut-on évaluer l'efficacité d'un antivirus (avant d'en subir les avatars : blocages voire pire infections..) ?
Enfin, je vieux bien déménager encore...

Dois-je aussi comprendre d'après ta réponse que je serais indemne de vérole ?Peut-être qu'un scan en ligne pour plus de sécurité serait indiqué?
Merci d'avance pour tes avis éclairés !

Bonjour jlpjlp,
Merci de te pencher si vite sur mon problème et désolée pour mes longs délais de réponse (très faible disponibilité hélas ces derniers jours...).
Je vais suivre tes conseils (ou du moins essayer ! :-)) ) dès que possible cette semaine(Je récupère mon fils ce soir avec son ordi après quelques jours passés chez son père).
Je te tiens au courant.
Merci pour ton aide... drôlement précieuse pour les ignares comme moi.
A très bientôt j'espère!

Hello jlpjlp

Tout d'abord un grand merci pour le temps que tu me consacres. Vraiment sympa !!! :-)

J'ai fait le hijackthis comme demandé en fixant les rubriques que tu m'as signalées.

Le scan avec Malewarebytes ne signale rien. :-)

Le scan complet antivir non plus :-D

Voici son rapport (RAS dans les warning il me semble. Ai-je raison ?)

Bonsoir Jlpjlp!
Une énorme MERCI pour tout. Je vais suivre tes conseils en supprimant AVG et en désactivant le tea timer de spybot.

J'indique mon problème résolu sur le forum.

Merci à toi (et aux autres pros) d'aider les néophytes.
Sans ce forum, la foule de renseignements que l'on trouve sur le site commentcamarche et l'aide que vous apportez, je serai dans une belle panade.

Bonne continuation et bons surfs
