Bonjour à tous,
 
J'ai un pb avec mon PC. Voici les symptomes : Il ram à mort... Lorsque je rentre dans ma session Windows, il m'indique que xxx.dll n'est pa trouvable ou je ne sais quoi, des pages de publicités bizarres (genre System Doctor) s'affichent toutes seules, des icones "casino" sont sur mon bureau sans rien demander etc. Bref il est bien infecté !
 
En plus de cela, lorsque je démarre mon ordi, une page noire s'affiche avec seulement écrit : Erreur lors du chargement du système d'exploitation.
Et après Hop, je peux plus rien faire. Mais j'ai trouvé une solution pour cette page noire, j'insere mon Cd d'installation Windows XP puis j'effectue l'option "recuperer" et j'entre les données : fixboot et fixquelquechose. Ensuite j'enleve le Cd, et le PC redémarre correctement mais toujours avec les même symptomes... Ensuite, quand je redémarre ma machine, l'écran noir revient alors je suis encore obliger de remettre le Cd Windows, et effectuer recuperer, etc.
 
Question virus, je m'y connais peu, alors...
 
...Que faire ? Comment faire ?  
 
J'ai utilisé quelques logiciels du genre : Spybot Ad-Aware et Clean-Up! qui ont fait du boulot mais pas trop.
 
Je vous remercie à l'avance pour vos futures réponses.

XIX. Concernant les logs Hijackthis : Désormais, tout topic créé dans l'unique but de balancer un log hijackthis à analyse sera systématiquement fermé. Pour analyser les logs, le site http://www.hijackthis.de/fr est parfait.  
Les logs hijackthis seront tolérés uniquement après une vraie présentation du problème, et une première analyse/diagnostic/dépannage de la part des autres forumeurs.  
 
le log risque d'etre mal vu

Ton 1er post était suffisant pour expliquer ton problème.
