I think I udnerstand what you're saying and I'd like to politely disagreee:
1. For law enforcement to log keystrokes, examine web logs and email records it no longer takes a warrant (in the U.S.). It's all part of the expanded power of law enforcement, and particularly the F.B.I. approved by Congress in the U.S. Patriot Act after 9/11.
2. In this instance, it is not illegal cause you are consenting to having the "agent" or service running on your PC.
Cheers.
