It's a good idea to NEVER>>>NEVER open ANY executable attached to an e-mail unless it's from someone you know ---AND--- you are expecting them to send it. A coworker recently opened what he thought was a joke message from a friend, executed the contained "pretty.exe" attachment and crashed our computer. The virus (among several other things) sent itself to all recipients on this guys e-mail list...his friends got the virus (worm) e-mailed to them from a known source! Be Careful!!!
