I have XP pro and have recently reformatted and found and removed the sasser worm from my computer. I downloaded every security patch that microsoft has put out. but i've been watching my cable modem and it's always sending information even if i'm not surfing or on AIM or anything. I typed "netstat" at the dos prompt and saw probably over 50 open connections. All random Ip addresses. I have enabled an XP firewall. What's going on?
