Apple Working Towards Flashback Solution
It only took approximately half a million users, including some employees, to get Apple to recognize the threat of the Flashback malware. The Mac manufacturer has since released a terse statement indicating that software to combat the infection is on its way. However, no definite release date was given.
If you do not want to wait for Apple's solution to Flashback, you can always go online and find a way to rid yourself of the problem by taking matters into your own hands. Arstechnica has a detailed guide on the how to confirm whether your computer has been infected, and how to remedy the situation with a few terminal tricks.
That probably is a better idea than waiting on Apple to "de-zombify" your Flashback-infected computer.
