I an effort to protect our current and future customers.
And, prevent win-spy software from being signatured by anti virus and anti spy softwares.
We are no longer are offering a Trial version.
These days more and more anti-virus and anti-spy companies dislike spy software and keyloggers.
They mislead our users that our programs are "trojan", "virus" or "malware", and make our customers confused by warning/removing Win-Spy impolitely. To avoid being "detected" mistakenly we have to frequently update our program.
Now we decide that we will only deliver our new product to paid customers since this will not only decrease the probability of false classification, but also greatly protect the privacy of our customers from being disclosed by anti-virus programs.
