Remove a VST Plugin that doesn't disappear from Plugin manager

Hi, I am trying to remove a VST plugin that I previously installed on my MacBook using their .dmg BUT even if I delete all the files inside my Vst, vst3 etc. folders (as I usually do) it is still showing in the plugin manager and when I open Logic Pro X it gives me an error saying that a plugin is not working correctly.. very annoying, how do I solve this? Anybody had the same issue before?
