In case you haven't seen, Microsoft released (earlier than expected) a patch for the WMF exploit. This is a "zero day" exploit, so Microsoft encouragew everyone to install this update IMMEDIATELY to affected machines.

please see Microsoft Security Bulletin MS06-001: http://www.microsoft.com/technet/security/bulletin/ms06-001.mspx

Because this is a picture exploit, we recommend notifying your friends/family of the available patch as well.
