How do I permanently delete Incredi-mail Icon from my desktop ?

[300zx]

First of all I want to warn you that I am barely computer literate. I can turn the computer on and do what I need to do. That being said, this Incredi-mail Icon turned up a few weeks ago. Everytime I boot up I get a message, Incredi-mail Icon is installed on my desk top, this will make it easier to install the program.
It seems ever since this icon appeared the booting up process takes longer. I have no intention of installing the program, how do I permanently get rid of this icon.
Thanks.
