High Risk A remote system is attempting to access your computer. What do you want to do?" I choose block and check always use this. Now it says that there are to many rules and to delete some. I have done this, what is trying to access my computer? any way to stop before norton pops up?
I have tried to block some of the ip address but there seem to be thousands.

Hello shammie,

any way to stop before norton pops up?
No. Norton is doing it's job, there probably is an option to stop the warning pop ups in Norton, I don't use it so don't know where it is.

I have tried to block some of the ip address but there seem to be thousands
Waste of time and effort - let Norton do that.

what is trying to access my computer?
The majority are Port Scans from infected systems - annoying but harmless as long there is a firewall to stop them.

One clue that these are port scans - the IP range falls into your own. ISP's mostly protect themselves at the ISP boundary, so what's comming thru is infected systems within the ISP's IP address range.

What Norton is doing is reporting every "ping" your computer gets from the net before auto blocking it, anyway. Click on "set alerting level" and change the setting so you aren't bothered with every internet activity "warning ".
