Website doesn't load unless I undo some immunization

[Who Knew]

* Operating System XP Home Version 2002 SP3
* Browser and Version Firefox 3.5.7, Internet Explorer 6
* Version of Spybot S&D and Date of the latest update 1.6.2.46, 2010.01.27
* where did the false positive occur Cannot reach www.vistaprint.com


If I undo the following immunization, I can reach the web site, but it doesn't load correctly. Windows>Global (Hosts)

If I undo the following immunization as well, I can reach the website and it loads correctly. Firefox>Name (default) (Images)
