This isn't fully clean, I'll say that right now. I tried it myself and found a new "addition" to my Start Menu known as OnLuck casino. I wasn't having that so I've already uninstalled it and checked the OneMX directory left - OnLuck's links were still there, as were the links to it on my Start Menu, the link on my Favourites and the link on my Desktop. I haven't been able to scan any spyware left yet but someone else might be able to.
To be fair to the program though, I suspect that it was the optional accelerator bundled in with the installation rather than OneMX itself (maybe someone can follow this up)
