While Macs have been notorious for being impervious to viruses – at least in terms of perception, while they were vulnerable, far more viruses were produced for Windows than OS X – their reputation for impeccable security is certainly being questioned now. Flashback, malware built to grab private information such as passwords entered in by users in applications, has evolved over time into a very dangerous piece of malicious software. In its beginnings, it required user interaction – through a dodgy looking Adobe Flash Installer – to lodge itself into one’s Mac.

A new tool has been released by security firm F-Secure which will check a Mac for signs of the Flashback Trojan and, importantly, remove it. Best of all, the app is completely free, that’s right, free!
