The reason SpyCop Cloak does this is because many times a Trojan, Bot, Keylogger, Worm or Spy Software application will try to find a specific window in the system so that they can access some of the contents of those windows.
Examples of this are when an application tries to locate the window that the user is currently interacting with, tries to find a specific window like a MSN Messenger chat box, tries to read the title bar of a window it doesn't own, tries to read the contents of a text box it doesn't own, tries to get a list of all active windows in the system, or tries to retrieve a list of all applications that are currently running.
Some programs need to do these things in order to function properly, but spy applications can use these techniques to monitor what you are doing with your system.
This is why SpyCop Cloak asks you if these actions should be allowed or denied.
If you trust a specific application you should probably allow the event to happen.
If you are not sure if it should be allowed or not, we recommend that you deny the event from happening. Your decision can always be changed later from the Block List screen.
