merci de ta reponse rapide mais que veux tu dire par "apparemment ok"
qu'il n y a pas de virus ou trojan ou autre?

voila donc si tu as le temps...j'attends ton aide,merci.
franckou.

Ton pc n'est pas infecté pour moi. Ralentissement ne veut pas dire virus.

re
j'ai reformater..
et la je fais une analyse avec spyware doctor,j'ai un trojan.lop_com
ensuite par exemple quand j'ecris la maintenant,ca arive apres je sais pas comment expliquer sa...puis quand je regarde une video sur youtube,elle est lag  
vraiment j'ai besoin d'aide!
merci

Pourquoi formater...
Quel est l'emplacement de l'infection détectée ?

bonsoir,
j'avais desinstallé spyware doctor et puisque tu m'as demande l'emplacement de l'infection je l'ai réinstallé mais la il ne le detecte plus...
Alors je voudrais savoir si je garde cette anti-spyware?
Ensuite souvent mon arriere plan change tout seul,par exemple il se met en noir..

Noir et tu peux le rechanger ?

Et bien quand mon ecran devient noir souvent il ne repond plus donc je le redémarre manuellement.
pour spyware doctor je le désinstalle?

C'est lécran tout entier ou juste le fond d'écran ?

re
c'est le fond d'ecran.

On peut vérifier.
