                             INFORMATION BULLETIN

                    Vellum 3D CD-ROM contains Mac MBDF Virus

July 8, 1997 19:00 GMT                                             Number H-79
PROBLEM:       The free Vellum 3D version 3.0 CD-ROM contains the Macintosh 
               MBDF virus. The virus is in the file: Vellum 3.0 CDROM:Vellum 
               3.0 Demo-Mac:Vellum. The file is dated 6/17/97. 
PLATFORM:      Macintosh 
DAMAGE:        Infects applications and the system. Repair may require 
               reformatting the hard drive. 
SOLUTION:      Do not run the Macintosh demo version of Vellum 3.0. Use
               current antivirus software. All other files on the CD-ROM, 
               including the Macintosh version 3.0 update and the Windows 95 
               and NT versions of Vellum are not infected. 
VULNERABILITY  Anyone running the Macintosh demo program who does not have a 
ASSESSMENT:    resident antivirus scanner will be infected with the virus. 
               Recovery from infection may require reformatting the hard 
               drive and reinstallation of all software. The CD-ROM containing
               the virus is being distributed at no charge and so may have a 
               wide distribution.

CIAC has determined that the demo CD-ROM for the Vellum 3D version 3.0
application is infected with a strain of the MBDF A/B virus. Vellum 3.0 is
a high end CAD package for the Macintosh. The CD-ROM containing the updated
version and some demo versions is being distributed at no charge by Ashlar
Inc. Due to the fact this is a free distribution, the infected CD-ROM may be 
widely distributed.

The cover of the CD-ROM contains the following text:

                       Vellum 3D
                      Version 3.0 
         for Windows 95 & NT and Power Macintosh
             (c)1997 Ashlar Incorporated.

The infected file is: Vellum 3.0 CDROM:Vellum 3.0 Demo-Mac:Vellum
The modification date of the file is 6/17/97

Users should not run the Macintosh demo version of Vellum. Other versions
of Vellum 3D on the disk, including those for Windows 95 and NT, and the
Macintosh update version (not the demo version) are not infected and can be
safely used.
