Good article taken from PCPitstop's Tech Talk
Had an experience trying to get an Open Source converter this last week from C/net and had crapware Search Protector included without any notice on the d/l. No uninstaller included, showed in registry and a string to programs but took a lot of forensic time to remove. This is a prob that's only going to grow in the future with unashamed greed on the web. C/net's off limits to me.
