Apple has just released a security update for OSX, the operating system that it uses on it’s PCs. This was released to combat the recent rise in attacks from variants of the MacDefender Malware. Just as the software update was released there is a new variant of the MacDefender Malware that is now in the wild. In safari on the mac, there is an option which will open “safe” files after they have been downloaded. This variant like MacDefender will work when this option has been enabled.
If you are on OSX Snow Leopard (OSX version 10.6.7), then I suggest that you download any updates as soon as you can. If you are still feeling somewhat unsafe, then I suggest getting some anti-virus package like Kaspersky Anti-Virus 2011 for mac. You can also have a look at ESET Cybersecurity for the mac.
To get the software updates from apple, you simply click the apple logo in the top left-hand corner of your screen and select “Software Update”.
Another fix that I can suggest, is not to use Safari as your web browser. Instead use Google Chrome, Opera, or Mozilla Firefox as your web browser.
Overall, I think that this is turning into another game of cat and mouse. Except for we don’t know as yet who is the cat or the mouse!
