Seems fine to me, you can unselect it during installation. It seems like a thing FJ added to the installer the earn some money if the user wants to install it (not unlike the ebay link in the past).
Thanks Stefan. I didn't notice an option to unselect during installation, but wasn't looking because none of the previous versions installed a toolbar. Just wanted to make sure nothing funny was going on with my machine.
The QuickStores Toolbar is included in the setup of MyPhoneExplorer. Its a optional component which can be unselected. The toolbar is integrated since a few versions. You can also uninstall the toolbar easily
