[cleanup error]

Question: cleanup.exe – how to remove cleanup.exe process ?

There was some problem of speed in My Computer, when I was monitoring the Windows Task Manager’s Process List and I found cleanup.exe. Does any one knows about cleanup ? Is it any system process or user process ? I have been using Norton Antivirus and it has not detected it as virus or worm, so is it related to any spy ware? Please tell me how this file cleanup.exe showed up and how can I remove this cleanup.exe process and will it generate any windows error ? Is there any cleanup.exe removal tool or utility available ?
