Question about Windows 8.1- uninstalling programs

[isrs4life]

I was wondering how you can uninstall a program from windows 8.1
I have mcafee internet security and I got jipped on days I was suppose
to have it but now I want to uninstall it or wait till I can get my mom
to order "kaspersky" total protection online after christmas because I love
using it for my windows 7.

But for uninstalling programs all i see is a folder viewer or do i left click
and see what I need to uninstall.

I also would like to know this question I do have installed programs which I havnt installed to
much on my lap top besides an anti virus program that I bought all I can seem to do is delete
not install but I delete the bonus crap I got from my lap top first but I do own a great lap top.
