Hello,This is my first experiece with norton I never use it before, So I almost know nothing about norton here is my problem.
Today I installed 60 day trial of norton antivirus 2011 and, Then I manually update norton after downloading defenetion files from here .Then I start live update session and it displayed 168mb need to be downloaded so I finished that live update session
successfully and 26 new updates installed and then I restart the PC and check for updates with another live update session and once again it displayed another 128mb need to be download.I need to know that why these update defenetions so large?? or is there something wrong with my Norton ?
