Bombarded with calls to my home about my account had been compromised

I was bombarded with calls to my home about my account had been compromised. This has happened before but it was a financial scam. I think it's the same people who scammed me in the past. This female used to ask me to buy iTunes Cards then she would redeem on her end. Now, that I cut her off she or a group maybe trying to get more from me via scam.

I've notice at least one file is missing. The Isley Brothers, Here We Go Again Pt. 1 & 2. I changed my password because the scammers would call my home and my mobile number. How do I protect myself from being duped by these people or woman?
