Do you have a firewall?
That's the problem with reviewing AV logs.  It's like looking in the garbage, there will be a lot of garbage in there.

These entries show that Norton is doing what it's supposed to be doing, stopping these incoming threats.  It's the ones that _aren't_ logged (i.e. are not caught) that you need to worry about.
