Just curious on the latest Spyware Doctor…

The new Spyware Doctor now activates its On Guard functions on the unregistered version… but I was wondering if this was really working, because on its older version a registration is required before it is activated. Is it really doing its job even in the unregistered version?

The big difference I saw on their unregistered version was that in the older version OnGuard is off but you can scan and delete any spywares it found. And in the new version, OnGuard is on but you cannot remove spywares it found after the scan and you need to register first to delete them.
Any additional comments or reactions? Because I’m not pretty sure w this and a little bit confused if the OnGuard is really working on their unregistered version.

tnx.
