Did you try to activate Windows XP firewall? If not, try this:
1. Start > Control Panel > Network Connections, right-click on Broadband connection (of course, connection type and name may vary) and select Properties from menu;
or right-click on Local Area Connection icon from taskbar's tray area, select Status and click Properties button
2. On the connection properties select the Advanced tab and then check the checkbox
However, to avoid prompts asking for
install Gator or other craps, you have to Disable all
ActiveX controls and plugins from Security Settings menu. I use to select Prompt only for
signed ActiveX controls
