Thunderbird 15. Update Lightning file Quarantined

Hi I just updated to Thunderbird V15.0 and NIS2012 quarantined the file calbasecomps.dll as discussed in this previous thread:  http://community.norton.com/t5/Norton-Internet-Security-Norton/Latest-Lightning-Update-calbasecomps-dll-Being-Quarantined/td-p/739168

 

What was the result? Do I just restore the file?
