From the day I had upgraded my NIS 2012 to NIS 2013 my computer is just becoming more sluggish.Norton 2013 is just like a worm in pc.I even can"t think that symnatec will launch just a Fake antivirus Program.It slows my computer to a extent that moving of 1Mb file takes 5 mins.I am using Win xp Sp2 Ram 2 gb And intel pentium dual core 2.7ghz proccessor.Now I am regreting why I have wasted my money on Norton I have to buy Kaspersky or Vipre or any other internet Security?
