IE10 64-bit vs. Norton Vulnerability Protection

Hello,

 

I've gathered that 64-bit browsers are not yet supported.  (Let's hope they are soon, now that IE10 is available for Win7.)  I also figured out that enabling Enhanced Protection Mode in IE10, which makes the tabs fully 64-bit, disables Norton Toolbar, Norton Identity Safe, and Norton Vulnerability Protection.  I can live without the toolbar and the identity safe, but I assume that vulnerability protection is the main protection of NIS while browsing. 

 

Which offers the best protection until 64-bit is fully supported:  running fully 64-bit IE10( with enhanced protection mode enabled and Norton Vulnerability Protection disabled) OR running IE10 with 32-bit tabs and thus enabling Norton Vulnerability Protection?

 

Thank you for any advice,
