Hi Leroy,
The AdwCleaner logfile shows us that MPC 's service is still present.
I'have already fought againt that service, and he is clearly well protected.
Actually, the best way to remove it, is to reinstall MPC completly, in order to uninstall it with it's own uninstall application.
The real problem here, is that some tools, like AdwCleaner, tries to remove it, but don't sucess completly...
