I'm trying to think where is have seen that before. Isn't that part of the message given for an unsigned driver? If so, I would think that the program may not be totally compatible with Windows 7. Looking at the tech specs, it says that it will run on Windows 7, but that doesn't mean that it is actually compatible.
I use O&O Defrag, mostly because I prefer the way that it work, but their newest version is supposed to be compatible with Windows 7, even though prior versions would run. It doesn't relate to your question, but when I asked their tech support about this, they said that the difference is because the new version defrags via zones, which the earlier versions didn't.
