受保护的程序运行时将抛出严重错误，可让人误以为该程序出了严重BUG而被系统关闭，从而很自然地阻止别人使用它。而自己却可以通过多种隐蔽的方式轻松解除被锁状态。

与通常的密码保护相比，它的保护方式更加含蓄且不易引人注意，既保护了私密程序又避免了节外生枝。

*** NOTE ***
新用户推荐购买Widget版“隐形锁”。 因为它不在应用程串行表中显示任何图标，所以会更加隐蔽和安全。

★ What's the best app protector?
Strong password? Of course NOT. The best proector would let prier not be aware of any protection. App Locker II is one such protector to protect your private apps.

★ How it works?
When launching a protected app, it will throw a fake crash error which may mislead guest user into thinking that your app has a glitch or something. So it can stop guest from using your protected app in a natural manner.

For owner, it provides several secret unlock methods to unlock it without a trace. Of course, it also provides a password protection with a secret input method.

? Please uninstall the trail version before install the pro version.
