I am personally using the Norton Deluxe edition, which I have used for over 3 years now and I had no problems with Norton. My favorite function that is included in the Deluxe edition is the SMART firewall.
Tip for consumers: If you have a plan, and want to switch then do not contact the support. They will just connect you to a gotoassist or teamviewer and help you from there, and I do not feel safe when I enter my credit card details when somebody is remote accessing my computer, so just turn off auto-renew, wait until your plan is over and buy the other plan you planned to buy.
I personally use Ebay because their are a lot of cheap items and products on their. I have never used Amazon, so I cannot say anything about Amazon. Note to reviewers: Do not post a bad review because of a seller you have encountered.
