Klez and some other worms use random filenames. Are you poisoning
*.exe? If not, then it can easily slip through, as most people only
poison specific .exe filenames.

I keep seeing these worms being announced, and I keep thinking about
my default-secure stance, and I keep thinking that I'm going to drop
*.exe into the recommended poison list on principle.

How badly would this annoy people?

I suppose I could maintain two lists, one with the .exe filenames from
the various announcements, and a shorter one with just *.exe -
any comments?
