Ed. Note: Mike and I were discussing the Flashback Trojan today, and I asked him if he could write up an explanation for you all, including what you can do to keep your computer safe. Thanks, Mike!
There has been some news about a Trojan software that can infect your Mac called the Flashback Trojan. To help prevent this, the first thing to do is make sure you run your Software Updates. To run your software updates, go to the Apple menu and select Software Update. Then just install any updates.
This Trojan uses something called Java on your computer and can infect you if you go to an infected website. You can disable Java in your web browsers. These instructions may vary depending on the version of your browser. If you can not find it with these instructions, let me know.
In Firefox, go to the Tools menu and select Add Ons. Then click on the Plugins tab and scroll down to Java Plug-In and click on the Disable button.
In Chrome, go to the Chrome menu and select Preferences. Go to the Under the Hood tab and click on the Content Settings button. Then under Plug-ins click on Disable individual Plug-ins. Then scroll down to Java and click Disable.
If you have any problems or want me to look at your computer, let me know.
