Removing Incredmail installer

Hello Experts,

I have a machine, that every time it starts up, tries to install the Incredimail package.  It first sits for a long time saying "Checking System Configuration". then a window from a program named "Incredmail Installation" pops up saying

"Unable to download installation script.  Make sure that you are connected to the Internet and try again later"

When I click OK on this message box, It gives me another message saying it will put a shortcut on my desktop to enable me to complete the installation later and creates the shortcut on my desktop.

The Incredimail program is not desired on this computer, so the complete shortcut is never used.  My question is, how can I remove this attempted installation from the machine startup?

Thanks
