Re: FL Studio third party plugins?
FL Studio uses two locations to read from for VST plugins. On Windows its under Program Files\VSTPlugins and Program Files\Image-Line\FL Studio\Plugins. The second directory I mentioned is typically where you will find the stock FX plugins and some of the stock Synths (i.e. Kick, Slayer, etc), so I'd recommend leaving that one alone.
See if that helps.
Also, some third party plugins actually install through the operating system, so (again on windows) check Programs and Features/Add Remove Programs (depending on which version of windows you are using) and try removing them from there as well.
Additionally you can change which directory FL Studio scans for plugins: Options -> File Settings. This can help you track down any stragglers.
Good luck, lemme know if that helps.
