Statistics.exe?

[fierce]

Hello... Having a problem where every morning between 5am-7am all my sites go down. Notice it only happens when there is a process running called Statisctics.exe. This process also takes up 50-60% of my cpu at any given time and restarts itself automatically even after I stop it manually. It restarted this morning and 3am and timed out every site between 5am-7am again today... Any ideas?
