Bonjour,  
je sollicite votre aide car depuis quelque jours j'ai remarqué une perte de bande passante  
Après avoir effectué des mesures sur un site je constate que mon debit est de 2Mb alors que jusqu'à il n'y a pas lontgemps j'étais toujours entre 7 et 8 Mb  
je ne m'en était pas rendu compte jusqu'au week end dernier ou j'ai voulu regarder un match sur foot+ via pc et là impossible , j'ai attendu un peu pour voir mais là rien à changer  
C'est pourquoi j'ai besoin d'aide ,car mes connaissance en informatique sont limitées  
 
je viens de lancer un rappor hijackthis et un message d'avertissement apparait:  
for some reason your system denied write access to the hosts file.If any hijacked domains are in the file ,hijack may notbe able to fix this.  
if that happens , you need to edit the file yourself.to do this , click start, run and type:  
notepadCWindows/System32/drivers/etc/hosts  
 
je vous met aussi le rapport
