Are > you sure that, say, SoundPlay, wasn't on the disk as well? 1. On checking with the coworker and his manager, it seems that the sound file was really a modified "Sound" cdev Control Panel File, which does contain executable code. Of course, anyone should have known that a cdev is executable. 2. There were other files on the disk, and they may have included a desk accessory or sound editor that may have also had nVIR. 3. The real problem is of course that he had Virex installed and didn't use it. 4. It is true that nVIR only infects executable code. But other Macintosh viruses affect other types of resources. Therefore: Check everything. 5. Free software is worth LESS than you paid for it if it has viruses. Robert McClenon Neither my employer nor anyone else paid me to say this.
