Mayascribe says this thing hits at 2 O'Clock Central everyday and only on SA. I've confirmed this with another source.
It hits Macs and PC's.
I have not had this happen to me yet, but I cannot recall if I have been on SA at 2 PM anytime in the last week.
I use Kaspersky security. If anyone else uses Kaspersky and has had this thing hit them, speak up.
From what's been described on Freya's instablog, it announces that your computer has been infected and starts counting fictitious virusus. Then it solicits a fix.
I've left a voicemail with SA and have yet to get a response.
If any of you have useful information, post it here. I'll tell SA to monitor this blog for feedback.
