>Thanks, Hilmar. My anti-virus program here at the office reports that it's protecting against several variations of the W32.Klez virus including a couple of Klez.H types. I'll have to double-check the home machine this evening. In any case, I stopped using the preview pane some time ago for exactly this reason. Next we'll have to go back to using pencils, paper and stamps.

Not necessarily. I just use commonsense and don't use Outlook at home (Agent 1.91 instead) and have no problems whatsoever.
I received four different Klez in the last week alone from 4 different senders in 3 countries. No infections on my end - ever!
Just be careful out there.
