I have always been impressed --- and thankful --- to Symantec and the Norton security products.
I'm using NIS 2012 and it caught a spoof email from services@paypall.com (note the two "Ls" in the email address) and sent it to my spam folder. I wondered why it went there, since none had been filtered before, until I saw the two "Ls" in PayPal. I looked at the message source and the spoof even included my name, which makes it really "appear" to be legitimate.
NIS is also great for blocking me from visiting potentially harmful Websites.
I just wanted to say thank you, Symantec and NIS 2012.
