Several of the machines which have probed me are also the same way.
However, I noticed that nearly all of them had some sort of "porn
dialer" installed. Coincidence? Probably since obviously these people
have no idea what is on their machines...

Bingo. I looked at some of the source addresses and saw windows
9x machines with publicly accesible shares (I could access them using
an empty username and password). In two or three cases, I checked
whether
the share was writable and it was. Having done a superficial examination
of system directories on those machines (they had a publicly accesible
share, ergo I was invited, wasn't I? <g>) I found some wierd files on
one
of those machines:

I downloaded 3 of them and they all seem to be compressed executables
having a common prefix, and there are some fragments of strings ("rom",
"y smt", ") with", "ESM", "Mime-", "-Typ", "quit" etc) in that common
prefix suggesting there is some SMTP implementation there--presumably
some kind of malware able to spread via email.

But I did not find anything similar on other machines I examined.
