I am running Windows XP SP2 with Zone Alarm firewall and AVG antivirus. I scan with Adaware and Spybot regularly. I have noticed that on Bootup, Zone Alarm alerts me that "svchost.exe is attempting to contact the internet". Zone Alarm indicates that the desination IP address is "239.255.255.250:1900". I have checked for running programs and found none in task manager. The only programs called to startup are AVG, TweakUI, and the Zone Alarm Client. All these programs are in manual update mode and not automatic. I am unable to determine why or what program is behind this attempt to contact this particular IP address.
How can I determine what actual program or dll is causing this action?
Thanks,
Jim
