The Flashback trojan has infected more than half a million Macs (and counting!). But until now, detecting it and removing it hasn't been dead simple.
F-Secure, the same company that previously posted instructions for detecting and removing Flashback via the Terminal, just released a free app to diagnose whether or not your system is infected, that will also scrub it if Flashback is detected. Go get it. [F-Secure]
