This is just an annoying problem with V9 that keeps looking for a Favicon for a thoughts which has a site (MagicCartButton.com) attached to it, and has been identified by Google as having malware. And then my AVG detection kicks in, but V9 keeps looking for it again and AVG kicks in again. REPEAT.
I needed to kill V9 to make it stop.
I finally just renamed the URL to make it stop.
