I had this virus in Germany, last year. Like Larry, the only way I found to eliminate it was to reboot in safe mode and recover the system to a about a week in the past.
That took care of it, but I tell you, I got a few more gray hairs trying to get past the purchase screens.... It's a nasty virus, to be sure.
Unfortunately, the less initiated, will start clicking on the free scan or purchase screen.
Never had anything remotely resembling this on my Apple ...
