Intrusion Attempt

Could someone translate this for me? I presume the Comodo name is just a coincidence.

At exactly the same time I got this from D+

It is Comodo signaling back that the port your computer tried to reach is not reachable after a request of your computer (type 3 code, code 3 of the Internet Control Message Protocol).

You probably used the Stealth Ports Wizard to completely stealth your computer; this will produce ICMP messages in your firewall logs.

To not log those type of messages follow this comment by Bad Frogger from point 11.

The activity together with alerts in D+ is most likely coincidental.

Thanks.
