When I upgraded as you did ( do we really have an option ?) I noticed all these changes going on with Norton. My attitude to these things is just let it happen and although one or two little issues come out they usually seem to get resoloved in time. If they say unistall the Virus checker I personally would as I understand you only need one. Two can conflict. Doing without the Sidebar is no real hassle- it usually just gets in the way anyway. Nothing on it you can't get from elsewhere.
