These look like MS messenger pop-up spam (starting at port 1025 and now
going into the mid/high-30s). The source address is likely spoofed. If
you take a look at these packets with ngrep or tcpdump, I'm sure you
find either advertising or a message saying your computer is infected
and you need to visit a certain web site.

I doubt the source is real, and wouldn't worry about it. That's the
stuff firewalls are supposed to filter :)

Cheers,
Frank
