drole de solution...

Salut,

Ecoute, il faut normalement commencer par un rapport hijackthis qu'il faudra analyser. Pour accélerer le traitement, je te propose ceci:
1. Fais le rapport hijackthis et poste un rapport; regarde par ici: http://www.libellules.ch/poster_log_hijackthis.php
2. Désinstalle l'antivirus actuel (si tu en as un); s'il est payant, désactive-le. Installe une version d'essai de nod32: https://www.eset.com/ Il détecte ton virus, j'ai vérifié. Mets-le à jour et fais un scan complet de l'ordi.
3. Reposte un log hijackthis.

bonjour et merci d'avoir répondu

Excuse-moi, mamm, j'étais dans la lune... Nuit blanche, mais bon. Je t'ai fait faire des manips complètement inutiles, ton PC n'a rien du tout. PAs d'infection, enfin, pas d'infection décelable via le rapport hijackThis ou via des symptômes quelconque.

Tout ceci car j'avais mal lu le début de ton post... :(

Alors, pour répondre à ta question: on ne peut rien faire concernant le lien envoyé via msn car ce n'est pas TON ordi qui est infecté, mais bien celui d'un contact. Derrière le lien se cache effectivement un trojan, mais tu ne l'as pas installé.

Sorry encore une fois pour cette folle perte de temps,
++
