System Idle         10%

You can then try to download autoruns (http://technet.microsoft.com/de-de/sysinternals/bb963902.aspx) and reboot in safe mode (F8). There search for the entry that runs this file and remove it

try running from a clean boot
run msconfig
in the startup tab, click disable all
in the services tab, click hide MS services -then click disable all
reboot and test
if no more high cpu usage, enable the programs and services in groups, or 1 by 1 to find the bad one
