A reliable source at Apple informs me that they have received word (currently unconfirmed by Apple) that there is a virus on the CD-ROM discs being given out at the WWDC. In particular, according to the attendee who reported it, the MBDF virus is contained in:
1. The FileMaker Runtime application on the Java Solutions for the Mac OS CD
2. The Neon software/NetMinder Ethernet Demo.sea on the WWDC Power User CD
Update: Greg Harlow, of Apple Computer, would like me to point out that the infected disc with the FileMaker Runtime file on it is not one that is being distributed by Claris and that the infected file did not originate with Claris.
