"svchost.exe" en plusieurs exemplaires...

Bonjour a tous, alors voila mon souci.J'ai remarquer que ma mémoire était utilisé a 42 pour cent alors que je n'est que Firefox d'ouvert.Après avoir regardé dans le Gestionnaire des tache je me suis aperçu que le processus svchost.exe est plusieurs fois présent (13 fois) et consomme beaucoup de mémoire.

Je voulais savoir aussi si c'était normal que ma mémoire soit utiliser de 1,26 GO. J'ai aussi une liste impressionnante de service dont je pige que dalle....
