How to get rid of CFP AV from XP?

I really don’t know how this happened but I very much need some help.
I installed CFP a few days ago. I don’t remember clicking or even seeing anything about installing Comodo AV.
I just uninstalled CFP and found your logo in my AV section of the security center.
And it states that I have 2 AV’s running.
So please tell me how to get rid of this.
I’m still a newbie and haven’t got a clue about things like this.
