  • It's Universal Plug and Play (UPnP) using Internet Group Management Protocol (IGMP) to look for either routers, networked printers or other networked devices.

    This protocol has been found to be exploitable on many router devices, so it's probably being blocked to reduce the risk.

    Unless you're having issues with either management or operation of your router or another networked device, I wouldn't be concerned.  Few devices actually require it for operation, it's usually simply used to allow easy identification and setup initially.

  • Onecare firewall will block when you try to ping other computers.

    ICMPv4 is the protocal which will allow users to ping other computer. (Ping is used to check the connection between the computers)

    Try to run a complete online scan. www.safety.live.com --->Full service scan.

  • To expand on onecare_Ravi's reply, you can either configure the firewall to allow ICMP outbound under the advanced firewall settings or you can ignore the log entries.
    As to what on your PC is trying to use that protocol outbound, it isn't clear from the log, but it can be any number of things. If you suspect malware, you may want to contact support. The online safety scan uses the same signatures as the installed copy, so I'd not go that route.

  • I need to find out why you continue to send out a notice that my firewall is OFF.  I never turn it off.  Why would it be off?

  • If you are receiving this notice from One Care and your firewall is turned off try the firewall repair tool - http://social.microsoft.com/Forums/en-US/onecarefirewall/thread/e67b1989-afd5-47e5-a393-3a551c7c7e60
