Viruses
This is a big reason to make SURE to update your systems. Apple included.
This trojan has been able to infect Macs due to a Java Virtual Machine vulnerability that has since been corrected by both Apple and Oracle for the PC world. Make sure you do your updates folks!
Analysis of a recent Java flaw exploited by the Flashback Trojan reveals that more than 550,000 Macs were affected in the U.S. and abroad, according to anti-virus vendor Doctor Web.
“This once again refutes claims by some experts that there are no cyber-threats to Mac OS X,” Doctor Web said in a Tuesday blog post.
About 56.6 percent of the infected computers, or 303,449, are located in the U.S., while 19.8 percent are in Canada, 12.8 percent are in the U.K., and 6.1 percent are in Australia, Doctor Web said.
Wisniewski also suggested that users install the Apple update, but insisted that “Mac users can no longer rely on simply updating their computers. Preventative protection is an essential defense mechanism to detect and thwart future attacks” from viruses and other threats.
