Can anybody advise what is triggering these alerts? Do I need to worry about them?

Funny, I get the same thing. Quite often from times when my PCs are turned off, like the middle of the night, or when I'm at work.
Any clue what these are? Am I safe to turn off the "trace_route" DoS protection to stop these, or shall I just filter them out of my inbox?
