Bonjour
Ceci n'est pas un virus...j'ai le même problème et j'ai l'antivirus Avast et il me dit que mon P.C est entièrement sécurisé ! Sinon je crois que c'est la mémoire trop courte qui fait ralentir...qu'il y a trop de fichier son ton ordi.Supprimes en quelques uns !C'est tout ce que je pourais te dire .

Bonjour,

J'ai un PC très performant et n'ai rien installé récemment, je doute que ça ne soit cela

J'ai oublié le rapport le voici

Au niveau de la mémoire j'ai 117Go de libres sur mon DD principal, donc je pense que le problème est ailleurs.
Je dispose d'avast en antivirus mais aussi avira.
Seulement je ne sais pour quelle raison, mais d'un jour à l'autre avira m'empêchait de me connecter sur internet, donc j'ai du suspendre la protection,

c'est sûrement ainsi que j'ai dû attraper une infection

J'espère pour toi que tu as trouvé la solution depuis tout ce temps, sinon voici le coupable :
C:\Users\Guss\AppData\Local\Akamai\netsession_win.exe
C:\Users\Guss\AppData\Local\Akamai\netsession_win.exe
Désinstalle Akamai et tu vas retrouver un débit normal.
Perso je l'ai vite identifier pour ce qu'il est une grosse merde. Il faisait carrément planter mon pc dès que j'essayais d'accéder au net.
Un petit redémarrage en mode sans échec et un peu de ménage plus tard tout va bien.
