@anonsubmitter, yes you are right. But, most free software downloaded on the Web come bundled up with useless crapware anyway. The YTD downloader box, if you don't want the app, can easily be unchecked while installing your main program. Unckeck all boxes for programs unrelated to the main program. If you need YTD or Hotspot Shield, they have a website where you can get them. No need to be bundled up to anything. They are already very popular. They both can be uninstalled very easily from Programs & Features, so they should not be removed by AdwCleaner. Removing Hotspot Shield this way messes up the Internet connection.
For those who don't usually pay attention while installing software, a program like Unchecky could be very useful. That way, you won't be flooding the malware removal forums all over the Web.
