File running CPU to the max

I have a rogue file that is constantly running my cpu to 100% every 10 seconds or so. The file is Winkhhn.exe. I have been getting memory dumps since this little fella has been playing around.

I am running an AMD Duron 950 with 256Mb ram on Win2000.

I have tried to locate the file, but search reveals nothing. I have found it in registry but am loathe to make any changes until I know what it is there for.

Please any help on what it does and how to stop it?
