It's not the first and it won't be the last time it happens either.
If I come to SUPERAntiSpyware.com.... chances are I'm looking to download and install SUPERAntiSpyware. If I wanted Google Chrome, ASK.com Toolbar, Uniblue Registry Cleaner, I'd go to those sites to obtain them. Imagine how much smaller these installers would be if they created an installer that just contains the product we came here looking for! *gasp*
