Based off your comments on the other answer, have you considered looking in your registry under the uninstaller information? If it's only showing in Programs and Features, that should give you a clue what it is and where it might be stored.
- Open Regedit
- Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall
- Look through the entries there to see if one matches the program you are seeing in Programs & Features
For 64-bit windows, you may also need to check under HKEY_LOCAL_MACHINE\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall
Also, if you are seeing it in your Start Menu, you could check C:\ProgramData\Microsoft\Windows\Start Menu to see if you can find a shortcut that gives you some clues.
