Performance issue with Wordfence

Hi

I was experiencing performance issues which were resolved after removing wordfence however, even though it isn’t listed in my plugins I am still getting reports from my website by wordfence. Does anyone know if this means wordfence is still installed or how I properly remove wordfence. It seems a bit stealth for something supposed to be protecting from stealth attacks, I don’t want it accessing my site without me knowing about it or having control over it
