Following yesterday's release of fresh Java updates to remove the Flashback malware system from Macs running OS X Lion and Snow Leopard, Apple today released a standalone Flashback malware removal tool to clean infections from OS X Lion systems without Java installed.
About Flashback malware removal tool
This Flashback malware removal tool that will remove the most common variants of the Flashback malware.
If the Flashback malware is found, a dialog will be presented notifying the user that malware was removed.
In some cases, the Flashback malware removal tool may need to restart your computer in order to completely remove the Flashback malware.
This update is recommended for all OS X Lion users without Java installed.
While the most dangerous method of attack for Flashback exploits a security hole in Java that Apple has now patched, various versions of the malware have also used social engineering and other tricks in attempting to gain access to users' systems.

With OS X Lion not having Java included by default, users of Apple's latest operating system who have found themselves infected through other means and do not have Java installed can use the new tool to clean their systems without needing to install Java.
The update weighs in at 356 KB and requires OS X Lion without Java installed.

Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released over 10 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided by practicing safe computing (see below). Also, Mac OS X Snow Leopard and Lion have anti-malware protection (http://support.apple.com/kb/ht4651) built in, further reducing the need for 3rd party antivirus apps.
Mac Virus/Malware FAQ (https://guides.macrumors.com/Mac_Virus/Malware_FAQ)
[LIST=1]
* Make sure your built-in Mac firewall is enabled in System Preferences > Security > Firewall
* Uncheck "Open "safe" files after downloading" in Safari > Preferences > General
* Uncheck "Enable Java" in Safari > Preferences > Security. This will protect you from malware that exploits Java in your browser, including the recent Flashback trojan (http://support.apple.com/kb/HT5244). Leave this unchecked until you visit a trusted site that requires Java, then re-enable only for your visit to that site. (This is not to be confused with JavaScript, which you should leave enabled.)
* Change your DNS servers to OpenDNS servers by reading this (https://guides.macrumors.com/Mac_Virus/Malware_FAQ#Why_am_I_being_redirected_to_other_sites.3F).
* Be careful to only install software from trusted, reputable sites. Never install pirated software. If you're not sure about an app, ask in this forum before installing.
* Never let someone else have access to install anything on your Mac.
* Don't open files that you receive from unknown or untrusted sources.
* For added security, make sure all network, email, financial and other important passwords are long and complex, including upper and lower case letters, numbers and special characters.
* Always keep your Mac and application software updated. Use Software Update for your Mac software. For other software, it's safer to get updates from the developer's site or from the menu item "Check for updates", rather than installing from any notification window that pops up while you're surfing the web.
That's all you need to do to keep your Mac completely free of any virus, trojan, spyware, keylogger, or other malware. You don't need any 3rd party software to keep your Mac secure.
If you still want to run antivirus for some reason, ClamXav (http://www.clamxav.com/) (which is free) is one of the best choices, since it isn't a resource hog, detects both Mac and Windows malware and doesn't run with elevated privileges. You can run scans when you choose, rather than leaving it running all the time, slowing your system. ClamXav has a Sentry feature which, if enabled, will use significant system resources to constantly scan. Disable the Sentry feature. You don't need it. Also, when you first install ClamXav, as with many antivirus apps, it may perform an initial full system scan, which will consume resources. Once the initial scan is complete, periodic on-demand scans will have much lower demands on resources.
Oracle DID fix the vulnerability 8 weeks before Apple. Apple just had to port the patch.
Even if that was to big a job for Apple they could have disabled the Java plugin on their platform as long as Java was unpatched. That amounts to making a software update that unchecks an option in the Safari preferences.
Even if that was too much of an effort they could have recommend to their customers to disable Java until further notice.
Sigh. Okay, this is going to take a little more explaining it seems.
Imagine I have make a recipe for a wonderful cake. I call this cake the Java-Cake. I make these Java-Cakes and sell them to cake stalls/shops.
Okay, now this is where you come in. You want to sell my cakes in your cake shop, a shop you call the Apple-Cake-Shop. But you wish to bake them yourself so they arrive on the shelf fresh and perfect. I agree to give you access the latest recipe as long as people are aware that it is a Java-Cake and not an Apple-Cake-Shop Cake.
For a few weeks everything is great. Then I notice that some people are having an allergic reaction to a certain ingredient in my Java-Cake. I improve the recipe and remove the offensive ingredient. By default, you get a copy of the new recipe, because it is part of the agreement that you have access to the latest recipe.
Unfortunately, you fail to take notice and continue to use my old Java-Cake recipe. Your consumers begin sending complaints of allergic reactions. Naturally, because it is a Java-Cake and made by me, the initial reaction is to blame me. Unfortunately, everyone else but you has the safe version of the Java-Cake, putting you at fault, because you (for whatever reason) failed to use the latest recipe.
When you agree to do something on behalf of your consumers, it is your responsibility. It is your fault as the owner of the Apple-Cake-Shop as you failed to update the recipe. You either need to pick up the game a bit or let me bake your Java-Cakes for you to ensure you have the latest recipe.
And that is exactly what Apple needs to do. Either accept its responsibility that it took on or let Oracle bake their Java-Cakes for them.
Get it now?
Same. I don't see how so many people are getting this.
Also, Apple didn't release anything for Leopard, right?
