Error message 8506, 422

I have just installed Norton Internet Security 2012 but now cannot access the internet. I have Error Message 8506, 422.

What do I need to do to restore my Internet urgently - I use my laptop for work

 

Hi ianmorgan64,

 

Did you have any other security programs installed prior to Norton or do you still have any installed ?  The error code indicates a possible conflict.  Pleaase let us knwo what was installed, how it was installed or if in fact it is still installed and we'll assist getting this cleared up for you.
