NIS 2012 error report

Having upgraded from NIS 2011 to NIS 2012 about a week ago every thing apparently runniing ok, on starting up online today I was surprised to have to manually enter usernames and passwords to some sites like Twitter and facebook which normally log me on automatically, then a few minutes in a box pops up from Norton Autofix saying an Error  3048,3 has been found and can't be fixed automatically.Following the link to #Norton customer support I was told a simple resatrt would probably fix the error which it seemed to do,but I was wondering what the NIS 2012 error report 3048,3 actually was and if it was connected to having to log in manually to these sites.
