I don't know if you're still having problems, but I may have a solution regardless. I had the same problem and did a bit of research. You can't exactly uninstall the program, and apple doesn't have a control panel with the add/remove programs option that you have on a PC. I may be wrong, but I believe the reason behind this is because everything is treated like an application. A program isn't removed by uninstalling it, but by throwing it away, which can be difficult to accept by PC users. Anyway...
You need to throw Trovi away. But there's sort of a process to it if you want to completely get rid of it, which you do.
1. Go to your trash.
2. Search for "Trovi".
3. Make sure the "This Mac" search option is chosen, instead of "Trash".
4. Click on the "+" by the save button.
5. Click on the first option box that shows up. I'm assuming the current option will be "Kind". Choose "Other".
6. A new box should appear. Search and select "System files".
7. You should now be back in the "Trash" box. Where "Kind" was once, the option should now read "System files". The option box directly to the right may read "aren't included". Select the option "are included".
8. You may now throw all that shows up in the trash. It will delete everything related to Trovi.
Once this is done you may close your trash bin and Trovi should be completely gone from your Mac!
*Quick note-the "+" may or may not show up in your trash after typing in "Trovi" while it is still open. Try closing chrome, safari, firefox, internet exploror, or any other search engines if this is the case.
Good luck!
