I removed Babylon Toolbar, cleaned the registry, ran a complete scan using SAS, then ran DDS.com again. "I Want This" did not go away.
The new DDS.txt file is attached along with a snapshot of the first three Google Chrome extensions that shows "I Want This" is enabled and is shown to be a "managed extension" which cannot be removed (the "Enabled" button is dimmed and cannot be deselected). Further checking shows that only Chrome is infected and that "I Want This" does not impact FireFox or MS IE.
I appreciate your help.
