there are a lot of computers trying to connect to my pc, Zone alarm only gives me a large list of ip's if i try to see what it was that tried to connect, nothing? In about 24 hours i got about 600 messages of something tried to access the internet, and about 200 something tried to connect to my computer. how can i find out what it is that is trying to access my pc. is this something that i should be worried about? anyone?
