This is what I have in my "Hold posts with header value matching a 
specified regexp" field.

I decided about a month ago that I will no longer tolerate attachments 
going through automatically. It does require me to be more vigilant, 
but it has stopped everything so far. As you can see, some of these are 
quite specific from repeat offenders that spam in plain text. But the 
generic ones are great for stopping virus attachments from going 
anywhere. I got two of my list regulars, one from Europe and one from 
the Far East to help me admin the list to let legitimate attachments 
through in a reasonable period of time. Generally, the delay is less 
than 30 minutes from the time one is posted until it is released.

I stopped four viruses these from going out today, which means that 300 
list members were spared virus attacks 4 times. So, I stopped Klez 1200 
times today by having to moderate 4 messages. Pretty good trade, if you 
ask me.
