My highest recommendation is you should disconnect your computer from the Internet to prevent further access. Get a USB drive and back up your sensitive data
(typically just /home/$USER). Completely reinstall your OS
. There's no telling what that person did so it's best not to chance it. They could have installed a program capable of circumventing any fixes you attempt (firewall or otherwise).
If you don't feel you're capable then reach out to your local Linux User Group (aka LUG). Those folks are typically willing to help out people in your situation. Where are you located geographically?
