Mac OS X is known to be repellent from viruses and Trojans for a long time now, but since the popularity of Mac has grown, virus creators have started to target the OS with new viruses. Just last week it was reported that a Flashback Trojan had infected 600,000 Macs.
Today, Apple has published a support document regarding the Flashback trojan that affects OS X computers, as noted by Jim Dalrymple of The Loop. Last week, a Java update was released to fix the security flaw that the virus was attacking. While 3rd party tools have been developed to test for the infection, Apple reveals they are working on their own tool to detect and remove the software.
In addition, Apple is working with ISPs worldwide to disable the servers that send commands to the malware. Apple also advises Macs running OS X 10.5 or earlier to disable Java in their browser preferences.
