hl.exe - how to remove hl.exe process ?

[hl error]

Question: hl.exe – how to remove hl.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 hl.exe. Does any one knows about hl ? 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 hl.exe showed up and how can I remove this hl.exe process and will it generate any windows error ? Is there any hl.exe removal tool or utility available ?
