Excuse the poor gramar and spelling I really am dyslexic.

Well even ISPs run portscans looking for "illegal" servers, and port scanning isn't illegal.
I think your ISP is full of it and trying to alay your fears.
What are the originating IP addresses? Many kiddies run portscans. I am on a cable modem network in a very small town of less than 10,000, I get on average 20 port scans a week. This is mostly L337 Haxor wannabees right here in town. Given the right script tools they can and will hose up your system ask anyone who has been rooted. Usually they are using class 3 or non-routable ip address trying here to sneak into a poorly secured boxes and home networks. The set up of the cable network here allows for these supposed internal or non-routable ips to be used. Your computer should be set to reject all outside class3 ip and outside non-routable addresses as a default, and not running netbios or open windoz shares at all if you don't need them.
Your ISP dosen't give a hoot for a residental accounts security so you have to do it on your own. Some don't give a flying leap for the commercial customers security. You need to learn it and protect your self. If a endloser like me can learn it anyone can. All most ISP care about is the check you send them every month.
