Free Mac malware removal tools (Flashback)

OS X, the operating system that powers modern Apple Mac computers, has been under attack by a threat that may have compromised more than half a million computers.

The Flashback Trojan is possibly the most prevalent malware threat yet unleashed against the Mac. So far Apple has made little comment but recently announced that it would create a tool to detect and remove the threat. It also suggests disabling Java, which seems a rather short-term and inconvenient solution.

Until that tool arrives worried owners can check their systems and remove the threat courtesy of anti-virus companies keen to help and, no doubt, hoping to make a good first impression on a significant new market.

UPDATE (12/04/2012): I have uploaded a ten year-old article I wrote about OS X security. Much of it is still relevant today, sadly.

UPDATE (12/04/2012, 1714): Added Symantec OSX.Flashback.K Removal Tool.

UPDATE (13/04/2012, 1058): Apple has announced the Java security update, which takes the extraordinary measure of disabling Java applets. You can turn them on but, if you don't use that feature for an unspecified period of time it will disable them again. I understand the logic of this approach, but it seems a little anti-user rather than anti-malware to me.
