The fight against Flashback continues. Kaspersky Lab said late Thursday that it had fixed the problems that caused it to suspend the Flashflake Removal Tool earlier in the day; the anti-malware program is once again available for use. Mac users can go to the company’s Flashback Checker site to see if their computer is infected.
Meanwhile, security company Norton unveiled its own Flashback detection and removal tool, available as a free download.
Both developments occurred after Apple—as promised—released another Java update for OS X, one that removes Flashback from infected Macs. The update, released on Thursday, can be accessed through Apple’s downloads support site or via OS X’s Software Update.
It’s been a busy week in the battle against Flashback. The Trojan horse malware may have infected more than half a million Macs; the latest version can install without a password if the victim merely visits a maliciously crafted website.
Apple on Tuesday said it was working with service providers to shut down the “command and control network” for the malware. Other solutions have emerged as well: Last week, F-Secure published a set of Terminal commands to uncover the exploit, and on Monday an independent programmer released a Mac app that can check for the infection as well.
