AV Companies will not intentionally attempt to prevent another software company (legitamate) from selling or distributing a product.

With that in mind.

If you knew what ISpy did, and they supplied a disclaimer, and you purchased it, why would an AV company detect it? It is a legitamate program not a Trojan.

If you are concerned monitor the installation and operation of the program with tools you can get from sysinternals...

Trojans are programs that are installed under the guise of a legitamate product but turn out to be of malicious intent. If ISpy advertises what they do and when you install it they make it obvous what your doing then an AV company would not see them as malicious.

If I install a key recorder or "Remote Management" software on my computer then that is okay. if you install it without my permission then that is not.

Something to think about...that is why Green Lantern is detected, it is installed without permission.
