ICMP packets are to do with 'ping' and 'tracert' commands. I'm pretty sure these are not

malicious communications. Maybe a more knowledgeable member could agree or not as

the case may be.

224.x.x.x is the multicast address. It could be allot of things. What aplications are running?

It's probably just your computer announcing it's presence, windows tends to do that on initialization of the TCP/IP stack and at random intervals. Whether you block it or not probably makes no difference whatsoever.
