Sending custom ping packets in windows

I've been looking around for a while but I havn't found anything yet so I'm gonna ask. Can you compress a file so it looks like an ICMP (or whatever) packet and you can send it like one, but it is really a trojan, or fork bomb or something else. I mean if you can destroy with a nuke, can you infect with a bio?

                                                      John...

not sure thats possible beacuse pings are only read if its actually a ping packet.

altering the packet will stop it looking like a ping so the computer wont know what to do with it… i think.

perhaps you could somehow add on to the packet so it reads the ping aswell as executing some code, bt im not sure if thats actually possible.

Ok, thanks, I'm still looking around, but I'll keep that in mind.
