Paradox: Antispyware is Spyware
I guess we have to live with that: The police can do what would be crime if done by anybody else. And antispyware is spyware.
Still, the following quote from the PestPatrol help file smells of a nice little paradox:
The first time you scan a client system, the Management Console automatically installs the Workstation Agent on the client. It runs in the background and accepts commands from the Management Console. The agent does not require user interaction or rebooting of client.
