Hi, I come from France (sorry for my english) and I tried almost everything to find a solution. I have this well-known problem with a SVCHOST process which take all ressources of my system.
I have a note book and the problem disappear if I stop windows XP and restart with the button and no when I use the restart fonction of windows.
Nobody find the solution for the moment…
I let you my Hijack LOG
