How to uninstall pepperzip when it doesn't show up in the list of programs?

I uninstalled pepperzip from my computer awhile ago but it seems like i still have it, i went to the control panel and clicked uninstall a program but its not showing up in the list but every time i try downloading a minecraft map its still a pepperzip file and i can't use it because it doesn't work, i'm sick and tired of this bs and want it gone but i can't find the program. How do i uninstall this blasted thing?
