Hi Joao.
I'm David, and I'm happy to help you.
Go to "Settings > Apps > Apps & features", and search for HP. See if HP Support Assistant is still installed.
If HP Support Assistant is not appearing in Apps & features, there may be some leftovers from the application.
See if you can completely uninstall it using Revo Uninstaller Free.

I hope this helps. Feel free to ask back any questions.
