I may be paranoid...but NIS 2010 for free!??

On thursday I was playing around on my desktop and then a box for Norton Internet Security2010 download comes up on my screen right about my bar icon of Norton 2007. I click to see what it is and it offers NIS 2010 download. I assume it's an update and click it.

It installs and everything seems cool and my intial scan it good.

 

Then at 6:30am est my World of Warcraft account is hacked.

 

I managed to resolve that issue...

 

but something has been weighing heavy on my mind.

 

1. Is this some kind of scam I've stumbled into and instead of NIS2010 I have a massive virus/malware/etc....

 

2. Is the hacking of my WoW account in some way related to the update from 2007 to 2010?

 

3. Am I just being incredibly paranoid since these two things just happened to occur at the same time?
