I just installed this on my computer and you need to be pretty careful before hitting the NEXT buttons on the install. Make sure you read them as some of them will allow the program to add some other toolbars into your web browser.
There is one where it only give you the option of an "express" or "custom" install and doesnt look like it will let you progress, but if you choose the "custom" you can deselect the add on stuff that will get added.
I hope that you haven't already put it on as it can be a pain to get rid of sometimes. Just be super careful and if you're not 100% confident then don't go ahead and it can wait until I get up there and can do it for you (OK I know this might eb a while but better than ahving unwanted shopping stuff on your computer)
