Is there a program for protecting facebook accounts from getting hacked?

someone has been hacking my account and i don't wanna delete my account and start another one and i also don't wanna deactivate it.
i once had a program that protected my account but it was on my old computer and i dont remember its name. DOES ANYONE KNOW ANOTHER PROGRAM??!!
Update: the hacker didn't hack through knowing my password. she has a program that helps her hack accounts by just writing their emails, i know that because i know the hacker and she told me how she hacked my account.
