Totally Un-installing IE

Hey guys,
I just switched to Mozilla, on my windows system about 3 weeks ago.
Once I read about Syko’s link about IE, I decided to totally get it off my system. So I deleted the files and whatnot, but I know I didn’t fully un-install IE, because sometimes I get pop-ups, using the IE program, while I’m on Mozilla!
Could someone tell me how to fully get rid off it.
I tried Add/Remove Progs, but it didn’t show up.
Thanks in advance!
