Norton AV Blocking XML (parser) in IE (Selligent online application)

Problem is with viewing website.

Just uninstalled Kaspersky AV and have loaded Norton AV.  Windows 7 64bit laptop.  Problem only occurs with Norton AV. Have 3 machines now with same problem.  Website is in Trusted Sites in IE and all active X etc enabled.  Website continues to work fine on any pc without Norton AV.  Once Norton AV is installed get the following error.  Have updated xml parser to latest version.  If I disable AV the problem still occurs.  Only by unstalling will the problem go away. 

 

Thanks,

Jasper
