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. _______________________________________________________________________________ CIAC wishes to acknowledge the contributions of Mike Shaw for the information contained in this bulletin. _______________________________________________________________________________ CIAC, the Computer Incident Advisory Capability, is the computer security incident response team for the U.S. Department of Energy (DOE) and the emergency backup response team for the National Institutes of Health (NIH).
