The gist of the story is that a crew out of the former Soviet Union is trolling the web with ‘free’ scare-ware that installs itself on Macs ( or Windows ) not even requiring a password intervention.

Once it gets rolling it, itself, generates pop-ups, an such like crazy. The victim is solicited for some bucks to get the upgraded ‘professional’ package – -which then simply gets rid of its own dirty linen.

The crew is changing the name and the program very rapidly, MacDefender already being relabeled at least twice.
