bonjour vetetistosore, voici le rapport du scan de f.secure!! j'ai un logiciel espion n'est ce pas?!!!!
mais tu sais, pour le problème du compte administrateur, j'ai le même problème même avec firefox!!! on me demande toujours mon mot de passe!! et quand je clique quand même je reçois le message suivant:

.....................................................
impossible d'ouvrir une session
Echec d'ouverture de session:restriction de compte d'utilisateur.Des raisons possibles sont des mots de passe vides n'étant pas autorisés, des restrictions sur les heures d'ouverture de session ou une restriction de stratégie a été appliquée.
OK
.....................................................
voilà!!
et pour f.seccure, tu m'as dit "( il te faut accepter les actives x barre jaunes clignotante)", moi on ne m'a rien demandé du tout!! je n'ai donc pas si c'est le bon scan!!!!!!!!

bonjour vetetistosore, c'étaientt des vacances en effet!! merci!
bref, je suis de retour...que dois je faire maintenant?

st lagiraf
bon j'esperre que tu en a bien profiter, il y a encore du taf mais aussi des questions mais pour l'instant ont va regarder les lignes qui ne sont pas correcte.

O4 - HKLM\..\Run: [drv wipe iso real] "C:\Documents and Settings\All Users\Application Data\Gram 32 Drv Wipe\lite atom.exe" a suprimer
O4 - HKCU\..\Run: [Vgamp3] C:\DOCUME~1\Ichraf\APPLIC~1\FLAWVI~1\send keep.exe
Inconnu a suprimer
O17 - HKLM\System\CCS\Services\Tcpip\..\{FC108B26-7326-49A0-B09E-4­24207C23116}: NameServer = 212.217.0.3 196.217.246.210 ATTENTION cette ligne contiend une adresse IP si c'est ton adresse garde la sinon suprime!!!
"MSIE: Internet Explorer v6.00 SP1 (6.00.2800.1106) pour finir" ce n'est pas a suprimer mais en fait et surtout pour te dire de passer sur une version plus recente ici:http://www.microsoft.com/downloads/details.aspx?FamilyID=9ae91ebe-3385-447c-8a30-081805b2f90b&DisplayLang=fr
une fois que tu aura fait l'installation de IE 7 tu va installer le SP2 ici:http://www.microsoft.com/downloads/details.aspx?FamilyID=049c9dbe-3b8e-4f30-8245-9e368d3cdb5a&displaylang=fr
cela ne resoudra pas tes problemes mais tu serra a jour au niveau securiter.
pour les questions:
tu a dit dans ton premier messages que tu venais de formater ton pc , la question et :a tu formater ou ecraser ton ancien systeme? si tu la ecraser cela expliquerai pourquoi ton pc est lent car quand tu ecrase un systeme tu n'efface pas forcement les infections precedentes
le formatage passe par une preparation du disc dur il est formater en NTFS normalement et patitionner en deux partie ou une ,cette preparation efface toute les ancienne donnee et le disc dur deviend vierge et apres l'installation de ton windows XP ce fait .
si tu a bien fait ses etapes confirme moi le merci !!!
pour la suite on va suprimer les lignes du log hijackthis et une fois que tu aura suprimer les lignes du log on passera a autre chose.
pour la supression tu fait le scan hijackthis "do a systeme scan only" tu coches les lignes comme dit au dessus sauf la ligne IE6 ou si la ligne de l'adresse IP est la tienne !!!
une fois cocher tu fait "fixe checked "et cela va suprimer les lignes
pour la suite tu va dans panneau de configue /bascule sur l'affichage des categories /performance et maintenance /systeme /restauration du systeme/coches la case desactiver la restauration sur tout les lecteur/appliquer /tu fait un redemarage du PC une fois qu'il aura redemarrer tu reviend ici et tu remet la restauration systeme en route, cela va effacer les traces de trojan qui peuvent rester dans la memoire de retauration systeme.
apres tu va dans panneau de configue /poste de travail /clic droit/proprieter /outils /defragmentation /defragmenter le disc /analyser et defragmenter
quand tu aura fait sa va ici :https://www.pandasecurity.com/en/homeusers/online-antivirus/?ref=activescan inscrie toi c'est gratuit et fait un scan de ton pc si il y a aute chose il va le trouver et desinfecte sur les grosse infection virus trojans ect il suprime ou desinfecte les problemes.
je te conseille de faire avant les mise a jour IE7 et SP2 car panda verifira si ton PC a une securiter fiable
voila pour la suite si tu a ton PC qui continue a etre lent il y a une autre chose qui peut en etre la cause, il ce peut que ton disc dur soit devenue trop vieux ou il a peut etre eter formater trop souvent ou il a vecu trop longtemp et a besoin d'etre changer car , pour te donner un exemple un dvd reinscriptible ne dure pas trop longtemp en qualiter une centaine de fois, donc imagine un disc dur qui a beaucoup moins de durer de vie voila ce qui peut expliqué la lenteur de ton pc
il y a aussi la configuration de ta memoire vive un truc est a faire tu va dans /panneau de configue/ affichage categorie /performence et maintenance/systeme /proprieter systeme/avancé/perfomances/parametre/avancé/modifier/et la si tu n'a pas la taille personnaliser tu peut la parametrer il te suffit de prendre la memoire que tu a exemple: si tu a 512mo de memoire vive tu multiplie par 1.5pour la taille initiale =768mo pour la taille max tu fait 512x2= 1024 mo une fois que tu a inserer les valeurs tu les definis pour que ton systeme les acceptes tu fait ok et appliquer on te demandera de redemarer ton pc voila je pense avoir fait le tour , si tu rencontre le meme probleme apres toute ses etapes il faudra peut etre formater ton PC mais attention a l'installation fait un dossier avec tout les setup de tes programes et une fois bien formater installe d'abord antivir avec la configue et fait la mise a jour et scan meme si tu viend a peine d'installer ton xp.
une fois que tu aurra fait l'instal de antivir je te conseille de faire l'installation du SP2 et de IE7 voila si tu a d'autre question je suis la jusqu'a mercredi et moi aussi vacances pour 1 semaine
tiend moi au courant a bientot

bonne vacance oui courte aussi , pour en revenir sur ton proleme de trojans il va falloir chercher sur des programes que tu a du reinstaller car il ne sont pas venus comme sa surtout apres un formatage , je m'explique si tu a des logiciels dit cracker avec des generateur de licence ou numero il te faut t'en mefier car ils peuvent generer des trojans sans que tu t'en apercoive.
AVG est un tres bon antivirus un des meilleurs gratuit j'aimerais que tu m'envoie le rapport de scan de avg et si possible que tu fasse un scan en ligne je vais te renvoyer un lien pour que tu pratique avec panda et bit defender des scan de controles tu va ici:http://www.commentcamarche.net/faq/sujet 11487 61 scans anti malwares en ligne pour xp vista#trend micro housecall
tu choisie ce que je t'ai recomander panda demande une inscription gratuite et elimie trojans et virus gratuitement pour le reste netoyage de tout le systeme cookies ect ect la il faut payer
et pour la suite bit defender tu sait comment faire pour l'avoir deja fait pour le probleme de ta carte si c'est la carte mere il est normal aussi que tout ne marcher plus comme avant lenteur de ton pc ect ect
je vais te demander de virer tout ce que tu a en logiciel avec crack et d'eviter de te servir de emule non pas pour le telechargement mais surtout d'eviter de faire des recherche de fichier gratuit sur les bitorrent et sutout alvarez .
il faudrai que tu me dise ce que tu a installer apres avoir formater et dans l'ordre dans lequel u a installer tout tes logiciel afin de voir celuis qui pourrais poser des problemes et de me faire passer le scan de avg stp....
a bientot
