I saw this post about KService after some trepidatious times re-installing XP and when my re-installed firewall gave me the thumbs up or thumbs down query, I went looking. For my part Kontiki was installed when I started watching AOL's online TV lineup at in2tv.com. IF you choose to do their download the HiQ video storage client this comes with it. You can watch the shows fine online, but if you go so far as to take them up on storing the hi quality videoclips on YOUR machine, they have you download this too. I am guessing its a typical usage stats report card client and it serves up usage stats back to AOL. But the concern is legit, if it's on your box, then you're running a server you didn't know about.  Now also in my case, I found an uninstaller in the ...\program files\Kontiki\   directory. I ran it after trying the above "stop" the services method which didn't work but I also didn't go so far as regedit either. I have since also deleted the ..\Kontiki\ directory where I found all of it, and told my firewalls to block and alert if it runs again. Thanks for the heads up.
