InprocServer32 Question

Ok I have this question because after a bit of running around today and leaving my computer on and having a 17 year old son (need I say more :) ) My firewall blocked outbound traffic as it should, but after running virus, spyware scans, I did a search of the reg. What caught me was the values because I've not really looked very deep in the CLSID, anyway what is this ThreadingModel with a value of "Apartment" entries I have? Geez sorry humor here I am a home owner :) Really a google search turned up a program to spy on COM http://www.develop.com/hp/jasonw/comspy/default.htm any other info besides what I've read at no answer at M$.
