The CNET secure downloader or QuickPDFConverter. CNET has a new policy that states to download programs you have to first download what they are calling a secure downloader or log in as a user and then download the program so they can track what you are using. When you look at the download button of the program they make the font for the secure downloader REALLY BIG and the font for logging in to download the true installer really small. It has been discussed in many of the forums. CNET is making the claim that if you do a custom install these should not happen. Your the second person to report that the secure downloader change things when told not to. The link below will point you to other person who had these things changed after removing the check from the boxes.

You can go to other forums and find other post that people have made on this but these should explain what is going on.
I downloaded QuickPDFConverter from CNET. In spite of doing a custom install and declining all options for toolbars and such, it installed a toolbar, tried to change my default search provider, and attempted to set something?? to start when Windows starts. Uninstalling QuickPDFConverter using Revo uninstaller revealed lots of Registry junk after the normal uninstall, and the unrequested toolbar was not removed.
I have tools in place, many downloaded from CNET, to deal with the unwanted aspects of this installation and was not hurt. Still, I expect better from CNET.
