dont worry about it i get my port hit over 50 times a day .i have backofficer friendly and it tells me everything that is going on.then i have visual route to tell me where it is coming should put up various security apps also besides your firewall just to make sure your safe,but like the other members have said it is just internet noise.usually advertisers trying to bother you..check with your isp to see if they have any hidden code that allows for port scanning as soon as you log on.remember isp's make there money from advertisers example:aol :-(
