MORE than 30,000 Australian Macs are believed to have been infected by a virus that entered through a hole in the security system. Mac users are now being urged to install the latest version of Java after Apple revealed their operating systems had been compromised. More than 500,000 Macs worldwide are believed to be infected with malicious software which can steal user names and passwords to websites you visit, ZDNet.com reports. Russian antivirus company Dr. Web said Australia is the fourth most infected country with 32,527 (6.1 per cent) machines believed to contain the malware. The malicious software program - known as Flashback Trojan – is automatically downloaded after users visit websites that have been infected. It then distributes a program that steals data such as user names and passwords. The Flashback Trojan is believed to have been around since September 2011 and has infected both Microsoft's Windows and Apple's Mac operating systems.
