A Russian security firm says it's found an alarming 600,000 OS X machines infected with the Flashback trojan.
The firm, called Dr Web, first said that it had found half a million infected computers but later upped the number in a tweeted message, where it added that some of the bots are in Cupertino.
Apparently the Java exploits used in the Flashback Trojan is catching on and researchers are starting to see malware that appear to be making use of the same route of attack.
Avira has released two free security tools - Avira Free Mac Security - offering virus and malware protection to Mac OS X users and Avira Free Android Security.
Their Android tool is not a virus scanner but rather aims to help secure the data on your mobile device and also enable tracking and retrieval should it go missing. Avira also offers an online account which you can use to track your phones location remotely and also set it into 'lockdown mode' in which the phone is restricted to calls to a fixed number and to emergency services only.
A new variant of the password-stealing Flashback malware aimed at Apple computers has emerged, which tries to install itself after a user visits an infected website, according to new research.
Flashback, discovered by security vendor Intego last September, is engineered to steal passwords for websites, including financial sites. Since its emergence, several variants have appeared showing its authors' innovation.
Apple has released a new Mac app named Configurator for managing groups of iPhone, iPad and iPod touch devices for schools, businesses or other institutions.
