Security Utility in 5.23 install package?

[Docqualizer]

I realize this may be in the wrong forum - and I apologize if it is.
When I grabbed 5.23 and installed it, I found a "New security program" icon on my desktop.
What is it, and why is there nothing about it on the web site? If there is, would someone please give me a link to it.
This is highly unusual for Nullsoft to do something like this, and I hope I am making "...much ado about nothing".

Thanks,
Lou
