The Service Source CD does not have a virus on it. The DART application on the CD is an older version (1.4). When DART 1.4 is launched on some systems (Macintosh IIfx and Macintosh Quadra series) running system software version 7.0.1, it presents a dialog box stating that there is a virus. This seems to be a problem with DART 1.4.
The latest version of DART (1.5) does not exhibit this problem. The Service Source group is aware of the problem and will be removing the DART application from future releases of the Service Source CD.
