Well, I guess it had to happen sometime:
The Flashback/Flashfake Trojan has been infecting Mac computers left and right. It disguises itself as a mainstream browser plug-in, but will steal your data if left unchecked. Antivirus companies estimate that more than 600,000 Macs have been infected so far.
Fortunately, Kaspersky’s free Flashfake Removal Tool will detect and remove this malware from your system. I recommend that all Mac users run it immediately.
Once your computer is clean, make sure you install the latest OS X update from Apple. It has a fix that will prevent Flashback/Flashfake from installing in the future.
