I purchased a 1 year 3-license subscription for Norton 360 on December 21 2013. I uninstalled McAfee and downloaded my copy of the Norton 360 a few days later. Installation was fine, no problems. The expiry date was shown as December 2014. The program has run quietly in the background for a few weeks and is much less obtrusive than the tiresome McAfee. So it came as a complete shock last Friday to find a message saying 'Your computer is at risk' and The Norton 360 subscription expired, 44 days after downloading it. In a word:- Help.
I'd hate to have to download any alternative i/net security software from the rivals.
