Hello folks -
I left my Lenovo notebook idle for some time last night. When I came back to it (roughly 1.5 hrs later) it was making a lot of noise as if a big process was running. I checked the running processes and logmon.exe had a very high CPU usage (~86+). I stopped the process, ran spyware and virus scans just in case, and found nothing.

Does anyone know what logmon.exe is? It's still in my processes list after a reboot the User Name is SYSTEM.

Anything I should worry about?

Any help appreciated, thanks.
