C:\Program Files\Kontiki\KService.exe is this a virus?

hello lovely people..

I have just downloaded 4oD, channel four’s on demand service. When i clicked the desktop icon my McAfee security flashed up saying
‘C:\Program Files\Kontiki\KService.exe’ is trying to run on your computer. I have blocked it for the moment because i do not know what it is. So i wondered if one you clever people could let me knoe whether it is safe to run. Incidentally, i can not get the 4oD to work. So i am assuming that by blocking ‘C:\Program Files\Kontiki\KService.exe’, i am stopping the service from working.
I only want to watch the original series of Lost…. please help. Ta
