“CNET EDITOR'S NOTE

YouTube Downloader includes optional bundled software that may trigger alerts from security software. YouTube Downloader has been tested for malware by the CNET Download.com team and meets our security requirements.”

I guess their “standards” don’t include the installer installing SearchSettings.exe from the wunderkinds at Spigot.  Once on your system, this little gem will (at a bare minimum) continuously change your default search provider to Yahoo.  Given Yahoo’s current financial woes it doesn’t come as a huge surprise, but still, I wouldn’t have thought they stoop so low as to launch flat-out hijacking attacks on user’s desktops.  

That’s the last app I will ever download from Download.com and the last hit yahoo will ever see from me.
