While the threat of the Flashback trojan has seemed to largely subside, Apple has released a tool for removing Flashback from older Macs running OS X 10.5 Leopard. A Flashback removal tool was released for Lion and Snow Leopard users a month ago, and now Leopard Macs can get in on the action. Yay for antivirus software!
Apple has also released a Leopard security update that automatically disables outdated versions of Adobe Flash player.
