Over 600,000 Macs have been affected with the Flashback trojan which obtains the usernames and passwords that you have stored on your computer. This could have happened without your knowledge by visiting an infected website. To find out if you’re infected, please follow the instructions at http://mashable.com/2012/04/05/mac-flashback-trojan-check/. We recommend that you use Sophos Antivirus which you can download at http://www.sophos.com/en-us/products/free-tools/sophos-antivirus-for-mac-home-edition/download.aspx. Apple released an update on April 3 to protect Macs against this trojan. It is good practice to perform Mac security updates as soon as possible. Please go to Software Update and install all updates for your Mac.
