Recently I am getting very frequent Security Alerts Boxes that pop upwith the High Risk Icon. The message says: "A Remote System is attempting to Access your Computer." Under that line there is an address that varies and then the Protocol is either UDP (INbound) or TCP. What are causing these alerts to suddenly begin? I have Windows XP and recently have updated to service pack 2. I also have Norton Internet Security 2004 installed. Is there a way to stop these frequent interuptions and alerts. I can't do anything until I respond to the message with Block or Permit.
