Svchost.exe occupe 100% du processeur ?

salut,
1./
Télécharger CCleaner (installe pas la barre de Yahoo ) :
https://www.01net.com/telecharger/windows/Utilitaire/nettoyeurs_et_installeurs/fiches/32599.html

lance le, dans nettoyeur clique sur lancer le nettoyage puis dans Registre fait chercher et répare les erreurs autant de fois qu'il y en n'a.

2/
On enlève le plus gros :

fait un scan en ligne avec internet explore, si tu as firefox fait:
démarrer -> executer -> tape : iexplore (puis valide)

(coche toutes les cases à chaque fois) :
https://www.eset.com/

à la fin colle le rapport : C:\Program Files\EsetOnlineScanner\log.txt

si ta besoin d'aide tu as un tutoriel ici : http://bibou0007.com/tutos-et-lexique-f45/tutorial-nod32-online-scanner-t128.htm

3/
Ensuite une fois fini fait un rapport hijackthis :
https://www.01net.com/telecharger/windows/Securite/anti-spyware/fiches/29061.html

tu le télécharges, tu le lances et tu cliquera sur le premier bouton en haut "Do a system scan and save a logfile"
tu colleras le fichier texte ici ;).

PS : Ne fermes pas le programme

re,
ton nod32 est légal ? à jour?
parce que le scan de nod32 en ligne supprime des infection alors que tu la d'installer^^

le hijackthis est propre

mais si ta Nod32 legalement :

1/ désinstalle le et redemarre
2/ supprime le dossier ( C:\Program Files\Eset\ )
3/ installe la version 3 ( Windows 2000/XP/Vista 32-bit - 3.0.667 ):
https://www.eset.com/

4/ met à jour et scan

ba si ta licence n'est pas à jour sa ser a rien puisque il pourra pas ce mettre à jour et je crois que tu pourra même pas le telecharger

Alors je devrais acheter une autre licence avant de continuer les manip ?

oui ou alors mettre un antivir gratuit (ex antivir : https://www.malekal.com/avira-free-security-antivirus-gratuit/
