qgis issue

I am a windows 7 user operating Norton 2011. As part of my studies I use the open source GIS program QGIS or Quantum GIS. This program is developed by a community of GIS users and as such is regularly updated with new attributes and versions. I have found that the SONAR function of Norton objects to QGIS. As soon as I update the QGIS program and attempt to open it SONAR quarantines and disables it and I have to tell SONAR to reinstate it. As regular updates are required, this becomes extremely frustrating. Is it possible to instruct SONAR that all forms of QGIS are 'safe' so that I no longer have to reinstate it each time I upgrade? If not, is it possible for future issues and upgrades of Norton SONAR to be programmed to recognize all forms of Quantum GIS as 'safe' and so avoid the difficulty each time an upgrade is performed. Otherwise Norton is currently a very good product and I would regret having to change.

 

Thank you
