WormScanner scans your local drives for the AutoStart 9805 worm variants (A through F) and will also alert you to unknown files with suspiciously similar properties.
It is based on published descriptions of the activities of these worms. It has not been tested on all variants of live worms. Worms may lurk inside disk image files, but unless the disk image is mounted, WormScanner will not be able to look inside.
WormScanner requires Color QuickDraw, which means that it will not run on machines that use the original 68000 processor. But since the known autostart worms are reported to function only on PowerMacs, that shouldn't be much of a problem.
Please read the documentation for further information.
