VantureBeat reports that antivirus firm F-Secure has released a free automated removal tool for the Flashback Trojan that has infected so many Mac OS X systems. The removal tool, available here, is in a zip file. Once you download and unzip it, follow the instructions to find the virus on your system.
If the removal tool finds the Trojan on your system, it will isolate it in a password protected file in your "Home" file. The password to this file is "infected." The removal tool will also save a log file of all its activities on your computer and give instructions for how to clean your system up.
