This was actually advised to you by another customer, looking at the topic you asked about this on. We may point out 3rd party items, but their use is always something that is at your own risk. Just thought I would let you know so that you are aware for anything else you install.
In the case of this one however, it does sound a little odd. What would generally happen is there is an actual app already installed, rather than there being files present. Are you seeing it both in uninstalled applications and in installed applications above it?
