I don't want my ex to ever see our daughter again. Is there anything I can do?

I have a beautiful 7 year old daughter that is the light of my life. She's smart, sweet, and as charming as ever. The only negative thing about my little angel is her father is a piece of s***. Literally. I was with my ex for 2 years before I got pregnant and I was so in love with him back then. We planned the pregnancy and he was so excited to be a father. He was there every step of the way. Her cut her cord, named her, signed the birth certificate and everything. We broke up for good when she was 5 months old but he was still a great father. He treated my daughter like a princess until she was 4.5. That's when he met his b**** and the only reason I call her a b**** is because that's what she is a b****. The split second he met his wife, everything changed. It started with him picking her up less and less and over a half year's time it went from "I can't get her this weekend" to "That's not my child." That thing turned his weak a** against his own child. This woman is so pathetic. She would talk about my child, who was 4, like my daughter had did something to her. I mean, she was so jealous of my daughter, a child. Most pitiful thing I've ever seen in my life. The last time he saw my daughter was her 5th birthday. He showed up late and said he could only stay a few minutes because his wife had something to do (the b**** was waiting in the car). He was there 10 minutes and my daughter walked up and said "daddy, daddy give me a hug." That piece of s*** looked my daughter in her face and said "you're not my daughter." My child cried for days. I cursed him out and was close to physically harming him. I told him to never come back. There was no point in letting him around after that, my child didn't deserve that. Those two continued to harass me after that, not about seeing her, but by leaving me messages saying its not his child and to leave them alone (funny, I never even spoke to them after that). They just recently had a child and posted pics on my Facebook calling their baby his "real" child. I just went to court demanding a DNA test just to end all their harassment proving him to be the father. This was 2 months ago, now nobody has anything to say to me (gee I wonder why). I don't want these people anywhere near my child and they have shown NO interest in being in her life since the DNA test came back. I there any way I can get his rights terminated?
