One is the new Flashback Removal Security Update. “This update removes the most common variants of the Flashback malware. If the Flashback malware is found, a dialog will notify you that malware was removed. In some cases, the update may need to restart your computer in order to completely remove the Flashback malware”, Apple explained in a security update.
The second is a security update that disables Java and Adobe Flash Player, favorite targets of Flashback that infected more Macs than any other malware in history.
“This update disables Adobe Flash Player if it is older than 10.1.102.64 by moving its files to a new directory. This update presents the option to install an updated version of Flash Player from the Adobe website”, Apple said.
Apple was criticized for taking so long to issue a fix for the Flashback malware, which began seriously infecting Macs in February and March, reaching a total of 700,000 Mac infections, according to Kaspersky Lab estimates.
That number dropped precipitously in mid-April, to around 30,000 Mac infections, after Apple released a patch for the Java vulnerability being exploited by the malware, as well as a removal tool.
