Sounds interesting, though I think someone sells a utility that with more functionality it may be a decent free alternative.

A quick Google search shows that this is a legitimate utility in the gaming community. You can judge for yourself as to its usefulness for Poser.  IMO, spend a minute or two of research before casting suspicion. - not that suspicion isn't usually good but check first, then give more informed opinions.

Before trusting anything like this for regular use, there are options like SandBoxie, ReturnNil, VirtualPC or VMWare that will allow you to test them without endangering your system.
