I tried ComboFix, not in optimal conditions and without reading some recommendations before... thinking there would be some warnings and steps where cancels if it is too risky. Bad game. Moreover, I was/am not infected.
So... I retrieved the control of my machine, with damages in services. I lost the "PolicyAgent" service, which I disabled because it is created and stopped very very quickly, and so services.exe saturates the memory.
But firstable I need to fix the DHCP Client, which always takes 100% CPU and doesn't do its job very well. Here are 2 event logs, activated for 1-2s, I'm not able to understand what it is about :
I don't know if you will see it in English, tell me if I must retry.
Hoping you can help me !
Edit : of course I'm on Windows 7 (x64).
