Why is "Registered copy" better than evaluation version?

The free trial version of Spyware Detector is designed to scan and detect the types of unwanted files you might have on your PC such as spyware, adware and key loggers. This allows you to fairly evaluate whether or not you believe Spyware Detector would be of benefit to you.

As it is a trial it has limited functionality. Trial version will not allow you to remove the spyware entries detected. The Registered copy will allow you to clean and remove the detected spyware and also provide you a continuous access to latest spyware definitions via Live Update.
