WTFHE.EXE????

Hi.

I am troubleshooting a pc with win 2000 pro. The antivirus picks up a file wtfhe.exe in the system32 dir and shows that it is an unknown virus. I have updated the av the the latest release. When deleting this file it just reapear in a couple of minutes.It seems like it is loaded in to memory or something???

Any help with this would be appreciated.
Thanks
