 Worst case, there is a very simple way
of getting rid of WDEF infections, and it's BUILT IN to the Mac!

When you insert a disk, hold down the Command and Option keys. You'll
get a message asking if you want to rebuild the Desktop file. Click "OK".
This will blow away any existing WDEF infection. The same can be done
for boot disks: just hold down those two keys after the "Welcome to
Macintosh" screen appears. You'll get the same dialog, to which you
respond in the same way. Nothing could be simpler. Rebuilding the
Desktop causes it to be thrown away, virus and all, and a new copy
built. Since WDEF doesn't live anywhere else, you're all set.
