fbs,
Do you d/l games or music? I believe that kontiki is more of a d/l manager than spyware, but I could be mistaken. Do you have Ad-aware? If so, run it & see if it detects kontiki. If you don't have Ad-aware, do yourself a favor and get it here
http://www.lavasoftusa.com/software/adaware/ . It's free, and works great at detecting & eliminating spyware. I run it at least once a week and usually find 5-10 spyware components on my puter.
