Hi and welcome to Norton Community, 0livia.
Before blocking the IP addresses, may I ask you a few questions?
*Do you have any tool bars and addons other than Norton Tool Bar in your system or browser?
*Where do you find this popup?
*Whats your current java version and operating system?
*Please check if you have any unwanted softwarer like custom download managers in your system.
These are to ensure your system is clean.
Just blocking an IP using firewall rules wont help much if the trigger is your system.
Keep us posted on this....
