If you read my previous post and after reading all of it, you would suggest me to stay with Norton as the protective tool of choice... I bought, as certainly all NIS2013 covering 3 PC. As stated in previous post, I installed 2 NIS2013 on the two new PC. After one day, for personal reason, I decided to reset the 2 PC to factory restore. I looked up in My account of Norton and it is showing only 1 download of NIS 2013 as available. If I decide to stay with NIS, I can easily re-install the 'last' download of NIS2013 on one of the 2 new PC. How will I be able to re-install the 2nd version of NIS2013 on the 2nd PC? Thanks
