UC à 100%

Bonjour,

J'ai un problème avec mon ordi. Mon UC est à 100%, j'ai passé mon antivirus (avast) et avg anti spyware mais le problème continu. Qd je regarde les processus qui me prennent le plus de la place, j'ai :
- iexplorer.exe : 73 000 ko
- iexplorer.exe : 34 000 ko
- msnmsgr;exe : 23 000 ko
- explorer.exe : 19 000 ko
- svchost.exe : 15 000 ko

Au total, j'ai 7 processus svchost.exe.

Pouvez vous m'aider?
