Is there a current virus threat that I should be aware of?


iMac, Mac OS X (10.5.8)

Stricktly speaking, no Virii on Macs yet, but there is Malware still...

 

Disable Java in your Browser settings, not JavaScript.

In order to avoid detection, the installer will first look for the presence of some antivirus tools and other utilities that might be present on a power user's system, which according to F-Secure include the following:

 

/Library/Little Snitch

/Developer/Applications/Xcode.app/Contents/MacOS/Xcode

/Applications/VirusBarrier X6.app

/Applications/iAntiVirus/iAntiVirus.app

/Applications/avast!.app

/Applications/ClamXav.app

/Applications/HTTPScoop.app

/Applications/Packet Peeper.app

 

If these tools are found, then the malware deletes itself in an attempt to prevent detection by those who have the means and capability to do so. Many malware programs use this behavior, as was seen in others such as the Tsunami malware bot.

The very best thing you can do is keep your version of OS X up-to-date. Apple has daily updates, many are security related. You are running a pretty old version of OS X (it's about 5 years old now), if your system is up to it I'd recommend upgrading to Snow Leopard or even Mt. Lion when it is released tomorrow. Of course your computer has to have the minimum system requirements to do so which means you need to see if your computer is up to the task.
