Norton Family Blocks All Internet Activity On Activated Windows Account

Hello,

 

I have Windows 7 Ultimate edition.

 

I have 2 accounts on Windows. Lets say A and B.

 

On account A, Norton Online Family is not activated and all internet activies works without any problem.

 

But on account B, Norton Online Family is activated, all internet activities blocked. I cannot even access google.com 

 

How can I solve this problem?

 

P.S: Account A is administrator on Windows. Account B is limited account on Windows..

 

Thank you
