kaza has a file which will be picked up by adaware programs. you can exclude it.
it is a necessary file for p2p kind of downloads.
reinstall kaza and dont delete that one file.
the media player also has few options as to get the licenses off the net or send info to you via the net etc. it works like a spyware so turn those options off.
I guess you can re-install media player if the sound doesnt work?
any ways I donno about that spydoctor but i use adaware (the latest version) and it has not messed up anything.
