Unable to purchase Norton Security (after blocking Silverlight). Simple as 1-2-3: I wanted to purchase NS, so I entered all my data, credit card details etc. very carefully indeed. Click to continue, nothing. Noticed above it said would you allow Norton use Silverlight or continue blocking it? No idea! I went to read about Silverlight and who needs it etc. and decided to select "keep on blocking" sin ce i got no idea what Silverlight is even after reading about it on Microsoft website.... something to do with government wanting to know our business perhaps? So after it got kept-blocked, nothing happens. Unable to purchase Norton Security. I feel this Silverlight is some kind of an extortion racket. Imagine, I hear them whispering in my ear: use Silverlight or we will create you many problems, you won't be able to purchase Norton, security etc. Will definitely avoid using Silverlight. And I am considering dumping all Microsoft products now.
