Click to expand... Hi Well, this depends on what firewall you are running. This explains XP SP2s firewall: http://www.microsoft.com/windowsxp/using/security/internet/sp2_wfintro.mspx and http://www.microsoft.com/windowsxp/using/security/internet/sp2_wfexceptions.mspx You can check your connections with TCPview from Sysinternals. http://www.sysinternals.com/Utilities/TcpView.html For example it is three and after a while four connections established when running MSAS - "check for updates". GIANTAntiSpywareMain.exe:2592 TCP X:1390 www.spynet.com:80 ESTABLISHED GIANTAntiSpywareMain.exe:2592 TCP X:1392 207.46.236.25:80 ESTABLISHED GIANTAntiSpywareMain.exe:2592 UDP X:1391 *:* GIANTAntiSpywareMain.exe:2592 TCP X:1393 207.46.236.25:80 ESTABLISHED

B Bill Sanderson Jun 27, 2005 #4 In general, if port 80, TCP is not open outbound, you won't be able to view web pages. However, this is somewhat more complex--but mainly in the area of corporate networks which may have transparent web proxies. The Windows firewall should not interfere with getting definitions, but third-party firewalls which block outbound by application, may.
